This wasn't the Luddite victory I hoped it would be, but making one's own mayonaise is most definitely a victory, and a tasty and satisfying one at that. I made my initial attempt with a hand whisk, but this attempt failed (although it did yield a very tasty almost-mayo sauce). I made another go, and decided to remove the variable of my own pathetic whisking and this time used a blender.
The ingredients to a basic mayo are pretty simple (the possible variations, however, are endless):
2 egg yolks
6 tablespoons of lemon juice or vinegar - I used freshly squeezed lemon juice
1/4 tablespoon of dry mustard
salt to taste
1/4 to 1/2 cup of some kind of oil - I used the last of my storebought vegetable oil.
Add the egg yolks, salt, and mustard to the blender, along with 2 tablespoons of the lemon juice. Start the blender on a low speed, and keep your eye on it. After a couple minutes, you'll hear the blender start to slow down a little, add a few drops of oil. Let it process, and add a few more drops. You should hear the blender start working harder and harder - slowly add more oil. The key here is to add the oil very slowly, and after you add some, wait a bit for the blender to do its thing before you add some more. Gradually, the mixture in the blender will really start to look like mayo and continue to thicken. Add the rest of the lemon juice, and continue to drizzle in the oil until it's all gone. At some point, the mayo in the blender is going to get as thick as the blender can manage on low speed. You could scrape down the sides, but at this point you run the risk of breaking the mayo (which can be fixed, but why do it if you don't have to?). I transfered the mayo to a glass bowl, and finished it by hand.
Now taste it... Go ahead...
Mine was mind-numbingly good. It was like I'd never actually tasted mayo before. I transferred mine to a mason jar, and stuck it in the fridge. My BLT's are even better than they've ever been before.
