I have no recipe for mayp.
I use one whole egg, lots of lemon juice, pepper, hot sauce, salt, and mustard, and one cup plus a little canola oil.
Whirl the egg in the food processor with half the other stuff (which you have mixed all together with a fork, except the oil).
DRIZZLE (this is key) half the oil, the add the rest of the other stuff, and finally, the rest of the oil. VOILA!
My brother uses a stick blender and has maybe a 20% failure rate. Using the food processor, I have a zero failure rate. Using a stick blender, I have a 100% failure rate.
I sanitize EVERYTHING with a mild bleach solution, rinse well, the prepare the mayo...don't want to mess around with that raw egg! By "everything", I mean the blade, the bowls, the spatula, and the final storage container, and anything else that might come in contact with the ingredients.
I tried it once with a hand mixer and it worked fine.
And that's all I know. My job here is done.
