A Mayo Guide

Before we get to microwaving the mayo, let us learn more about it first.

Mayonnaise is made from egg yolk mixed in oil, vinegar, or lemon added with some seasoning. It has a slightly whitish or yellowish color and appear thick but creamy.

We regularly use mayo to taste and moisten sandwiches, burgers, or salads. It is also use as dips and can be made the base of other types of sauces or condiments.

I believe we commonly use it to prepare Coleslaw or Devilled eggs. It goes well with our chips, fries, potatoes, and bagels. We cannot list all mayo recipes, but some of the must-try dishes with mayo that you can easily prepare are:

  • Creamy Potato Salad
  • Chili Mayo on Vegetables
  • Tuna Sandwich
  • Tartare Sauce
  • Lobster Rolls with Lemon Chive Mayonnaise

Mayo is famous for making food tastes even better, but do you know there are other things you can do with it apart from eating it.

How Mayo is Made?

Some people will not go through the hassle of making their own mayonnaise. They think it is very time consuming and it is difficult to make it thick like the readily available mayo in the market. So, most people would simply buy it off the shelf.

To help you realize that making your own mayo is easy, we summarized the steps for you. This is easy to follow and surely will result to that thick and tasty homemade mayo.

How to make your homemade mayo in 5 easy steps.

  1. Prepare eggs, cooking oil preferably olive oil or any plant-based oil that is almost tasteless, mustard powder, salt, lemon juice or vinegar.
  2. Mix all the appropriate amount of ingredients-eggs, oil, mustard powder, and salt using a food processor or you can whisk them manually until the mixture become thick and creamy.
  3. Add lemon juice or vinegar to the mixture. I prefer lemon though using vinegar is also a good option.
  4. Whisk your mixture again for a few minutes and there you have it, your homemade mayo.

Remember that in making your own mayo, you can choose to use the egg yolk only like how it is commercially prepared, or you can use the whole egg and it will be just the same.

Some people do not consider making their own mayo at home because of the risk of salmonella in fresh eggs and buying commercially made mayo is safer. So, if you worry about salmonella on fresh eggs for your mayo, you can buy and use pasteurized eggs instead.


Mayonnaise and Microwave

There is a notion that once mayo is reheated it becomes slightly toxic, but it was just a tell-tale.

Mayonnaise can be served hot or cold, and it is safe if you need to reheat or microwave it.

Why is it claimed that microwaving or reheating mayonnaise is safe? Let us check on the three factors why it is OK to do it in the context that we bought the mayo off the shelf.

  • The eggs used are pasteurized.
  • Acidity brought by the lemon juice or vinegar prevents the growth of microorganisms.
  • Mayonnaise itself is not toxic but the growth of bacteria in it makes it unfit for consumption.

Why are these three factors described for off the shelf mayonnaise, what if it is homemade?

Because we are sure that the eggs used in preparing the mayo are pasteurized so there is very low risk of bacterial growth in it.

If the homemade mayo used pasteurized eggs, then those factors also apply. There is just a higher chance of bacterial growth if you simply used fresh eggs on your mayo, but it does not mean you cannot reheat or microwave it.

It is important to note that how we store the mayo can contribute to its freshness or spoilage.

How do I store mayo to prevent spoilage?

Reheating and microwaving mayo does not cause it to spoil but storing it improperly does. That is why we should also know how to store it correctly to prevent bacterial growth.

These suggestions will help you store your mayo for a much longer shelf life.

  • Be sure that it is in an airtight container with lid.

Using an airtight container with lid is very important to prevent air from sipping in the mayo container. Air can carry particles and even bacteria that can grow in the mayo and spoil it. This is also why consuming the mayo may cause health risks.

  • Store it in freezer at 40 degrees Fahrenheit or below.

When not in use, it is important to put it in the fridge because it prevents the growth of food-born microorganism.

  • Reheat only a portion that you need to use and do not reheat it several times.

Get a portion of mayo that you only need for consumption to avoid reheating the lot. Reheat it only once and do not overdo it to avoid greasy mayo on your food.
