Hey everybody! This is Kenji Lopez-Alt And I'm going to show you a super simple way to make great homemade mayonnaise in two minutes or less using an immersion blender here's how we do it. Start by breaking an egg into a cup that's just big enough for the head of your immersion blender to fit There is no need separate the egg or use just use the yolk here by the way. Next, add a teaspoon of Dijon mustard. This adds flavor, but more importantly it helps the water, and the oil, and the mayonnaise to emulsify into a creamy sauce. Add a tablespoon of fresh lemon juice for acidity. Fresh squeezed is definitely the way to go here. And if you would like you can also add a clove of minced garlic at this point. Top it all off with a cup of neutral oil like canola or vegetable oil. I dont recommend extra virgin olive oil for this, because the violent action of the emmersion blender can turn it quite bitter. Season it all with a big pinch of salt and a few grinds of black pepper. You can use white pepper, if you don't like the look of black pepper specs in your mayo. Now here's the fun part, lower the head of your immersion blender to the very bottom of the jar then turn it on. As it spins, it draws oil down into a vortex, forming a thick, stable emulsion as you slowly lift it. Lift it up and down a few times to stabilize, and you've got mayonnaise.
