I love making my own mayonnaise. I made my first following Alton Brown's recipes from his show. The videos are posted on foodtv and are well worth watching if you are new to making your own mayonnaise. This is my latest variation. This is easy enough to do that I generally make my own whenever I know I'm going to want mayo for a few things. I only use store bought mayonnaise because it lasts forever in the fridge. Once you make your own mayonnaise, you won't want anything else.
