Mayonnaise is generally made slowly, blending eggs and oil together over the course of five to seven minutes. However, that has all changed with one of my new favorite kitchen tools: an immersion blender. You can find these just about anywhere that sells mixers and blenders. They’re great for soups and batters, but what they do best is emulsify oil and eggs—in about 20 seconds! A note before you begin: This recipe calls for raw eggs. People with compromised immune systems should not eat this. For those of you who do choose to make the mayo, use the freshest eggs possible. The best choice is to get eggs directly from a farm or a reliable vendor at a farmers market; but eggs from cage-free, pasture-raised chickens, which are sold in most grocery stores, are also generally safe.
