What is mayonnaise?
Mayonnaise comes from the French. And what a hit it has become! Now it is made and available the world over. Mayonnaise or mayo is a thick, creamy, cold dip or dressing. It is widely used as a dressing in salads, as dips with fries, or as a condiment or sauce in sandwiches, burgers, and hamburgers. Mayo is also a thick saucy emulsion from drizzled oil into raw eggs. Emulsification, a procedure that forces different liquids to form a suspension and stay stable, is a natural phenomenon and is the force behind mayo.
Chemistry of Emulsification
Often, you will have two or more liquids that are un-blendable. They cannot mix as they do not dissolve in each other. Take oil and water as an example, as these do not dissolve. But emulsification as a step helps fat/oil droplets suspend in water to form many well-known emulsions. An acid among the ingredients breaks down the fat into tiny bits, which can be dispersed throughout the watery liquid. For emulsification to work, it needs fat and water. We have refined oil here for fat; the liquid is the watery substance of egg yolks. It also needs an emulsifier and stabilizer. The proteins present in egg yolks act as emulsifiers that help bind the fat and water molecules. Also, eggs have a natural protein called lecithin. But you need an agent to break down the proteins and release lecithin. Here, lemon juice is the acid that helps break the proteins in egg yolks and stabilizes the mixture. With eggs providing the emulsifier, mustard does the magic of stabilizing the emulsion. Dijon mustard is creamier, but you can use regular mustard. But what triggers emulsification? The mixture of oil and eggs needs to be whisked continuously. You may use a conventional whisk or hand-held blender, or food processor. While the whisking or blending needs to be slow or short, the trick lies in slowly adding the fat/oil, more like drizzling the oil into the mixture while whisking it. You may know or wonder at all the science behind this simple procedure. Worry not; making this happen and creating rich, creamy, and delicious mayonnaise is easy at home.
Right technique – Food processor Vs. Stick blender
I have made mayo many times using a variety of methods. I find making mayo using a stick blender is the best method. This technique is FOOL-PROOF. You can not go wrong with this. Get creamy mayo each time. The conventional method is to whisk manually or use a food processor. If you use those, you must drizzle or add some oil ( a teaspoon at a time) while the mixture emulsifies. The trick here is to let the increasing mixture emulsify and maintain the suspension when more oil is added. So what is the risk? Many times, the mayo may split while you do this. Once it does, the entire mixture is wasted. And this happens more time than many cooks let know. You do not have to play slowly with the oil using the stick blender method. Just add all the ingredients and start blending. That saves time and effort. An important technique here is to blend it in short bursts. Blend for 10 seconds. Rest. Blend again for 10 seconds. Rest. Keep doing that until you see the emulsion formed. Do not run stick blenders for long since they heat reasonably quickly. It takes six bursts and a minute and a half to get the emulsion. What can be easier and quicker than this? Congratulations! You did the job without taking the trouble and care of drizzled oil. You get this right every time.
Ingredients
Whole eggs – We are going to use the yolks and whites together. You can buy raw eggs or pasteurized ones. Olive Oil – Get good quality refined extra-virgin olive oil because you will benefit from the taste and flavor. Plus, refined oils will not have a strong or rancid taste that will break up the mayo. You can use other neutral-flavored and refined oils like avocado, sunflower, or canola. Dijon Mustard – Added for both flavors and to keep the emulsion stable. Lemon Juice – helps to keep the emulsion stable. Salt – Brings out the flavors of the mayo. Sugar (optional) – This is optional, but a little sugar balances the tartness of the mayo beautifully and tastes delicious.
How to make mayonnaise at home
Take a glass container or steel bowl with a narrow bottom. I used a stick blender to whisk away the mixture. This type of container shall also work if you use a food processor or blender. Pour the eggs into the bowl. Add all the oil to it. Add salt, sugar, and lemon juice to the bowl. Now keep blending in short bursts until you see it mixed well. Keep blending in bursts until you see the emulsion formed. Pat yourself and serve rich, creamy mayo in a variety of ways.
Tips to make the best mayonnaise
Many recipes including the original version call for only yolks but whole eggs are used widely too. It makes the task easier as you do not have to separate them. Additional egg whites in whole eggs have more protein too that helps in emulsification. If you are worried about health risks from raw eggs, use pasteurized eggs instead. Not only are they healthier, they have a longer shelf life too. Use a refined oil as anything else carries a risk of splitting the mayonnaise. Refined oils do not have a strong taste or flavor which would be too overbearing in the mayo which is mostly oil and egg. You may also use a blend of refined or light oils. You may substitute lemon juice with vinegar. These acidic ingredients help in breaking down the proteins and add flavor too.
Store
Once made, you need to seal the container, which keeps mayo. Also, it is advisable to keep it in the refrigerator. You can store mayonnaise in the fridge for not more than 4 days. Since homemade mayo uses raw eggs, they tend to last shorter than store-bought commercial mayo made from pasteurized eggs with a longer shelf life.
