How to Make Immersion Blender Mayo
Add all Basic Mayonnaise to a wide-mouth pint-sized mason jar in the order they are listed, starting with the lemon juice and ending with the oil. Allow the to settle for 20-30 seconds.
Insert your immersion blender, pressing it firmly to the bottom of the jar.
Turn it on high speed and hold it steady for 20 seconds. You will see the mayonnaise magically start to emulsify and thicken from the bottom up.
Once the bottom is thick and creamy, slowly tilt and lift the blender up and down to incorporate the remaining oil from the top until the mixture is fully combined and smooth.
To create a flavored variation, transfer the fresh mayonnaise to a bowl and stir in your desired variation until well combined. Store in an airtight container in the refrigerator for up to 2 weeks.
Keep the immersion blender pressed firmly to the bottom of the jar until the bottom half has emulsified. Lifting it too early can cause the mayo to break.
