This recipe was featured in the Cool Tip: Failure is the Father of Invention (or How I Learned to Make Foolproof Mayonnaise)... and is astoundingly easy to make!
1 Whole Egg
Juice of 1/2 Lemon
1 Teaspoon Salt
1 Cup Neutral Oil (we use the Mediterranean Blend from Costco)
Any other flavors you might want to add (e.g. garlic, mustard)
Put all the ingredients in a jar that is large enough to fit the head of your immersion blender, the ingredients, and has some room to spare.
Wait about a minute to let the egg settle to the bottom of the jar.
Put the immersion blender all the way down in the jar and turn it on. Leave it there for about 20 seconds, or until you see the oil start to emulsify and “climb” the sides of the jar.
Pull the blender slowly up in the jar, and then move it slowly up and down to incorporate all of the oil in the emulsion.
That’s all there is to it--Enjoy your homemade mayonnaise!
