Place the egg yolks, 1 teaspoon of lemon juice, the mustard, and the pinch of salt in a bowl or in the bowl of your food processor or blender.
2 egg yolks, 1 teaspoon Dijon or homemade mustard, 4 teaspoon fresh lemon juice, 1 pinch of salt
Start whisking/blending everything together, and then start slowly drizzling the oil in.
1 cup of your chosen oil
Continue pouring in the oil slowly but steadily. An emulsion will eventually start to form, and you’ll be able to pour in the oil more quickly.
Using a blender, immersion blender, or food processor makes it very easy, but if you decide to whisk it by hand, you’ll have to whisk quite vigorously for the whole process to prevent the mayonnaise from separating.
Your mayonnaise should be quite thick when all the oil is incorporated, and you can then add the remaining lemon juice and blend it in with the mayonnaise.
Enjoy and refrigerate the leftovers!
