The Science of Sauces: How to Make the Perfect Mayonnaise



Perfect Mayonnaise

Sauces have the ability to transform any food. They can boost the taste of your food and act as appetizers as well. It’s quite easy to buy sauces from the market. But many people across the globe who use them in large amounts on a daily basis make them by themselves. These people mostly include restaurant owners, cooks, and fast food makers.

There is a science of making these sauces. Without knowing this science, you cannot make it by yourself. Proper heating, mixing, and adding different ingredients at the perfect time are some main things to care about. Evaporation of the right amount of water from the sauce to make it thick is also necessary for this process.

But do you know that not all the sauces need to be cooked for making them? Some sauces can be made even without any heating. All-purpose green sauce can also be made without cooking, but mayonnaise is the most famous sauce that can be cooked without cooking. The mayonnaise price in Pakistan is not too much, but its vast use in almost every fast food from burgers to pizzas supports the idea of making it by yourself.

Making mayonnaise is not a difficult task. You can do so at your home with the proper gadgets and knowledge. But making a perfect mayonnaise is an art. Different things are required to do at different times to make it perfect. Following is a complete method that can lead you to make a perfect mayonnaise at your home.

Basic Science Behind the Process

The basic scientific process behind mayonnaise manufacturing is emulsification. Emulsification is simply mixing up two liquids to form a mixture. Egg yolks along with oils are mixed to form a homogenous mixture called mayonnaise.

If you fail to mix them up completely to the point where emulsification occurs, then your mayonnaise will not be perfect. It might not get a thick shape and its taste can also be worse.


The main thing about any sauce is its ingredients. You must have complete knowledge about the ingredients. A knowledge about their percentage in mayonnaise according to each other is also necessary as it will help to save it for a longer duration.

You must have seen various YouTube videos that claim that by watching these you can make mayonnaise at home. In these videos, it is shown that you can add anything to the mayonnaise to change its flavor. According to these videos you make mayonnaise from a chicken flavor to any spicy flavor.

But this does not happen in this way. The reason behind this is that some ingredients can change the nature of the chemical process required to mix fats and egg yolks. Some possible flavors can be added but this will decrease the storage duration. A classic mayo can be kept safe for more days than any other flavored mayo.

Oil, egg yolk, salt, and vinegar are basic ingredients of mayo. Vinegar is used to enhance taste and assist in the mixing of the ingredients, as it is acetic acid indeed and can boost the mixture formation.

Egg Yolks

In almost every YouTube video it is shown that the egg white is used in the mayonnaise. But this is not the fact, as the basic thing is egg yolk. You need to spare it from egg white to make mayo from it. Mayo receives its color and most of the taste from the yolk. So the color will change from pale yellow to off-white.


First of all, take the egg yolks in a bowl. Add vinegar to it, this will increase the water portion and help in mixing. You can also add the lime juice in place of vinegar. The next step is to mix it by hand or using an electric beater until it becomes viscous. You can add salt for taste, but make sure that you don’t add too much salt. This will ruin the taste of your mayo. Add oil dropwise throughout the process.Above is the complete method, but if you want to save your time and don’t want to make it at home, you can buy mayonnaise online at a reasonable price.

Can You Zoom In On A CCTV Camera System?




For CCTV camera owners, the zoom feature is one of the must-haves of your security system. This ensures that any suspicious activity will get caught in full detail, especially if a certain incident happened somewhere around the range limit of what the camera can capture. With the right camera specifications, the zoom feature can play a more important role since zooming will not get the footage’s quality affected if the camera specs are really good.

Read about how much CCTV Cameras cost.

Take note that not all CCTV camera systems are capable of providing a good zooming feature, since some models are not built to have a zoom-in-and-out feature on their lens. But take note that those that have the zoom feature have more imaginable advantages than those who don’t. In this article, you are going to learn what are the types of CCTV cameras that have this feature installed, as well as the two main types of zoom found in the finest CCTV cameras in the market.

Read about how CCTV cameras work at night.

PTZ Cameras: The Best Camera For Zooming

The PTZ Camera is what you need if you really want a camera that has the capability to provide a zooming feature. PTZ cameras were made since most of the finest CCTV camera types do not have the pan-tilt-zoom feature. The pan-tilt-zoom is a mechanism that allows the camera to move on any direction you want the camera to view, and you can also zoom it in for a clearer means to capture scenes that are quite far if the lens are set at default magnification.

The PTZ cameras function so well just like a CCTV camera, but with the capability for you to completely control the camera. This is one of the best types of cameras that you can have if you own a business or a large property like a warehouse, but with guards that are monitoring the while security system. In this way, your personnel can have an easy time capturing any suspicious activity because they can take a closer and more detailed look if they spot something even when the PTZ mechanism is not yet in use. Talk to your local PTZ camera installation expert about the best locations to put your cammeras.

The Two Types Of Zoom

Now that you’re familiar with the best type of CCTV camera available in the market, you should be familiar with the types of zooming features that you can access not just with PTZ cameras, but with other CCTV systems that have  decided to add such a nifty feature. Here are the following:

Optical Zoom

This is the standard zoom mechanism present in some camera lenses. Basically, this is the physical means of zooming an image through the lens, whether you are using a wired or wireless camera. This is the feature that’s present in PTZ cameras and other high quality CCTV systems. The quality of the optical zoom may or may not get affected if you zoom closer. This depends on the megapixel of the camera lens, as it determines how much pixels will be in use when a footage gets zoomed in.

For the best optical zooming features, it’s always best if you can get the maximum magnification possible for zooming in with the camera. Security cameras that range from 3x to 20x optical zoom. Though there are even models that can provide up to 50x zooming capability, but these are extremely expensive as they are more on the higher-end technology scale compared to those that have 20x optical zoom.

There are three known types of optical zoom camera lenses. The first one is the manual varifocal optical zoom cameras, which is known to be manually adjustable even before you start operating the camera to capture some footage. These are oftentimes waterproof as well, ensuring utmost durability, and has a knob to help you adjust the varifocal lens on the camera when needed.

The next one is the Motorized Optical Zoom cameras, which can let you adjust the magnification of your zooming features remotely using an app that’s connected to these cameras. That’s why this is present in most IP cameras rather than the other CCTV camera types. Last is the classic PTZ camera that we highly recommend if you really need the best camera for your zooming needs.

Digital Zoom

The other one is the digital zoom, which is basically a feature present in the surveillance app only, rather than being present on the camera’s specifications. This does not assure a quality that’s exactly as good as the optical zoom, but it can still do the magic of zooming in more details. However, digitally zooming a video usually affects the quality of the footage, which often leads to a blurry image. This is not recommended when zooming on very far areas of the video.

With all of these in mind, it is safe to say that technology has gone a long way in making our cameras more useful than ever before. Just remember that zooming is not impossible with CCTV systems, as technology improves over time in a way that will make our lives much easier.  If you are in doubt about what camera to get you could always get advice from your local CCTV installers. They will be able to advise you on what is good for your specific circumstances.

The narrow end of a charger features a foil covering that’s broken to release the gas. This is usually done by a pointy pin inside the topping dispenser. The laughing gas in chargers (or nangs) is additionally used as an oxidizer in hybrid model rocket engines. The metal cylinders used as containers are about 6.3 cm long and 1.8 cm wide, and are rounded at one end with a narrow tip at the opposite end. Referred chargers’ walls are about 2 mm (about 1/16 inch) thick to withstand the great amount of pressure of the gas contained within said container. Their interior volume is 10 cm3 (about 0.6 in³) and most brands contain 8 g of N2O struggling .

Although used cream chargers are non-refillable, they are 100% recyclable where steel recycling programs exist. In a more easier to understand term, whipped cream chargers are made to be a steel cartridge or cylinder that can contain nitrous oxide gas. N2O laughing gas canisters come with a foil acting as a cover on its tapered end which is punctured to release the gas with pressure. The sharp pin outfitted in the whipped cream dispenser is then used to break the seal. Moreover, hybrid type rocket engines also make use of N2O cream chargers as an oxidizer. However, the foremost basic use of N2O cream chargers is to form high-quality topping for dessert toppings and decent beverages. Besides, they’re going to additionally be used for other culinary applications like imparting desirable texture to some specific components of sweet and mouth watering dishes.

Top tips and tricks to improve your photography



improve your photography
  • Quality of content is more important than quantity

This means that you don’t have to take a lot of photos in order to get good ones. Just take the time to make sure each photo you take is well composed and thought out. And always delete the bad images; you don’t need them!

  • Never shoot in auto mode.

Auto mode does not allow you to control the settings on your camera, so you’re not getting the best photos possible. Learning how to use your camera’s manual settings is essential to taking great pictures.

  • Understand how to use your camera’s manual settings

This means learning things like aperture, shutter speed, and ISO. Each of these settings affects your photo in different ways, so it’s essential to understand them all.

  • Use Excellent Equipment

With the help of excellent equipment, you can take your game to the next level; good equipment like a high-quality camera with a stable tripod and right lens can differentiate you from other photographers. Buy a camera from a top brand and not compromise on quality if it comes under your budget.

  • Composition is key

 A well-composed photo is more appealing than a poorly composed one. Learn the basics of composition and practice using them in your photos.

  • Learn the basics of light and how it affects your photos

There are three types of light: hard, soft, and diffused. Each of these affects your image in totally different ways, so it’s essential to learn them all.

  • Experiment with different techniques and styles

Learning different techniques and styles is a great way to improve as a photographer because it will teach you new things about light and composition that you may not have previously known.

  • Post-processing is essential to great photography.

This means editing your photos after they’re taken, either through photo editing software or just uploading them onto an app on your phones such as VSCO cam or Pic Stitch.

  • Use the rule of thirds when composing an image.

One way to improve your photographs is by using the rule of thirds, which states that images should be split up into nine equal pieces vertically and horizontally, with four points where these lines intersect. It is believed this will result in a more attractive composition than one where the subject appears dead center. The article provides examples of how this can be applied.

  • Ensure you have enough light

This is something most people do not realize; however, if you want good-quality photos, you need to have sufficient lighting. Cameras are susceptible to light, and if there is not enough of it, your photos are likely to come out blurry or underexposed. When taking photographs outside, make sure to shoot in the early morning or evening when the sun is low in the sky for the best results.

  •  Use a tripod

When taking photos in low light or of landscapes, using a tripod can help to ensure that your images are crisp and clear. Tripods also give you more freedom to adjust settings without having to worry about shaking the camera.

  •  Shoot in RAW format

If you have the ability to do so, shooting in RAW format rather than JPEG will give you much more flexibility when editing your photos later on. Files contain more data and allow for more adjustments to be made without resulting in a loss of quality.

  •  Pay attention to the details.

Often it is the small details that make a good photograph great. Make sure to take the time to notice things like the light, shadows, and textures and capture them in your shots.

  •  Use filters

Filters can be used to add creative effects to your photos or to correct specific issues such as distortion or poor lighting. They are a great way to experiment with your images and can help you achieve the look you are after.

  •  Experiment with perspective

One way to create more exciting photographs is by playing around with perspective. Try shooting from high up or low down, or get close to your subject for a more dramatic effect.

  •  Take lots of photos

This may seem like an obvious one, but the more photos you take, the more likely you are to get a good shot. You can permanently delete the ones you don’t want later on.

  •  Learn about your camera

It is essential to know how to use your camera inside and out if you want to be able to take great photographs with it. Read the manual and experiment with different settings until you find what works best for you.

  •  Shoot in RAW

When you shoot in RAW, you’re capturing all the data your camera sensor sees. This gives you a lot more flexibility when it comes to editing your photos. You can bring out details that were hidden in the shadows or recover lost highlights.

  •  Use a Tripod

Tripods are essential for sharp photos. They help keep your camera steady, which is especially important when shooting long exposures or slow shutter speeds.

  •  Use a Remote Shutter Release

A remote shutter release allows you to take photos without touching the camera. This eliminates any chance of camera shake, which can result in blurry photos.

  •  Get to Know Your Camera Settings

Understanding the basics of your camera settings will help you take better photos. Experiment with different settings until you find what works best for you.

  •  Shoot in Manual Mode

Shooting in manual mode gives you more control over the final image. It takes some practice, but eventually, you’ll be able to capture the exact photo you want by adjusting the shutter speed, aperture, and ISO.

  •  Use a Lens Hood

Lens hoods are an essential piece of gear for any photographer. They help protect your lens from scratches and moisture, and they also help reduce lens flare.

  •  Clean Your Camera Sensor

Dust on your camera sensor can cause streaks and spots in your photos. To avoid this, regularly clean your camera sensor using a blower brush or a cleaning kit.

  •  Use a Flash Diffuser

If you’re using a flash, using a diffuser will help soften the light and create more natural-looking photos. You can buy an off-the-shelf diffuser or make one yourself out of some household items.

  •  Shoot in Low Light Conditions

Low light conditions can be challenging, but they also offer opportunities for creative photography. Experiment with different shutter speeds and ISO settings to see what works best.

  •  Practice, practice, practice!

The best way to improve your photography skills is to practice as often as possible. Try shooting in different conditions, and play around with the various elements in your photos.
