If you have an immersion blender, making mayonnaise without sugar in it is very easy:

(And it tastes way better than commercial mayo!)
I love this author's recipes; it's the opposite of the normal recipe-preamble-slop. All of the stuff before the actual recipe is relevant information. In more complex recipes, he goes over the testing and process that led to the finished recipe. It's a wonderful view into the world of recipe creation.

You can also make mayonnaise with a whisk.
Awesome, I'll give that a try. What I like about it is that you can use whatever high quality eggs you normally use instead of the cage eggs that mass producers will use. Until now I had to resort to vegan mayo.
