Step 1

Combine the milk, lemon juice, garlic, and pepper in a 2-cup glass measuring cup. Using a handheld blender (or a blender), buzz on high for 30 seconds until frothy.

Step 2

With the motor running on high, slowly pour in the oil a few drops at a time, and gradually increase this to a fine thread, moving the blender up and down, until the mixture thickens lusciously and resembles a soft mayonnaise. You may need more or less oil.

Step 3

Season with salt to taste. The mayonnaise will last up to 1 week in the fridge.
