One of the helpful time savers I use in my kitchen is an immersion blender and it is so easy to make mayonnaise from scratch, you can have it made quicker than finding the mayo shelf at the grocery store and putting a jar of it in your shopping cart.
I use all virgin olive oil when I make it to avoid oils made with genetically modified ingredients. I also eliminated the sugar. I may try it with a small amount of stevia as a sweetener but we find it very palatable without any sugar at all. And I only use a dash of cayenne pepper in my version.
I use a wide-mouthed canning jar and just blend everything up in it, use a small rubber spatula to get the excess mayo off of the blades and then put the lid on the jar and into the refrigerator it goes. I then wash the immersion blender by blending a small amount of warm, soapy water then I dry it and put it away. Total time used is about 5 minutes from start to finish.
What could be easier?!
You can get your own immersion blender from Amazon and have fresh, healthy mayonnaise from scratch in a flash.
