I'm sticking with storebought because I don't even like mayo that much, and homemade is terrible to me, not to mention wasteful. Even a small batch just made with one egg yolk, I'd never use even half the recipe before I wouldn't trust its safety.

I did like the bacon mayo (google 'bacon mayo paleo'), but again, it makes too much. As much as I love bacon, I don't love bacon mayo put on everything!

I tried making mayo out of non-hydrogenated lard. Not impressive, though someone who's more seasoned at mayo-making might get better results.
