What Is Mayonnaise?

Everyone knows about mayonnaise, but what really is it? Mayonnaise is an emulsification of oil, egg, and acid – in our case, lemon. When you add these ingredients to the blender in a certain order and in a certain way, the high-powered action of the blender whips it all together turning it from a liquid into a spreadable solid. You can make this low-carb mayonnaise by hand, but you’ll need a good whisk, a large bowl, and plenty of muscle.

Ingredients

It doesn’t take much to make this keto condiment and you probably already have everything you need!

  • Oil – Avocado oil is your best pick, or use olive oil.
  • Egg – Use a fresh, whole egg. If you’re worried about using a raw egg, look for pasteurized eggs from your grocery store. They’re less likely to cause any issues.
  • Dijon mustard – You can also use any smooth mustard.
  • Lemon – Just a wee bit of fresh lemon.
  • Salt and pepper – Just a pinch to season it.
