Because I know SOMEONE is going to ask:
1 egg yolk
1 tsp lemon juice
1/2 cup liquid bacon fat
3/4 tsp mustard
salt and pepper
Combine the egg yolk, mustard and lemon juice in the small bowl of a
food processor or in a blender and process to mix. Season with salt and
Have the bacon fat liquid, but not hot. With the machine running,
gradually the bacon fat until the mixture starts to stiffen and emulsify,
about 2 minutes. Once it starts to emulsify, you can add the fat more
quickly. If the mayonnaise is too thick, just blend in 1 teaspoon of boiling
water to thin it. Taste and adjust the seasoning.
If God didn't want us to eat animals, he wouldn't have made them out of meat.
