Whisk the yolks, vinegar, and mustard: Start by whisking egg yolks, vinegar, and mustard until the mixture is slightly foamy. This step is crucial as it introduces air into the yolks, setting the stage for a stable emulsion.
Gradually add the oil: Now, the magic of emulsification! Slowly drizzle the oil into the yolk mixture in a very thin stream, whisking constantly and vigorously. The key here is patience and control. Adding the oil too quickly can cause the emulsion to break, leaving you with a separated mess rather than a smooth mayo.
Whisk until thick: Continue whisking until all the oil is incorporated and the mixture has thickened to the desired consistency of mayonnaise. It should be velvety and hold its shape.
Season to taste: Now, tailor it to your taste buds. Add salt, freshly ground black pepper, and a bit of lemon juice for a bright note. Remember, seasonings are personal, so adjust according to your preference.
Refrigerate: Once your mayonnaise is ready, cover it and refrigerate immediately. Homemade mayo doesn’t have the same preservatives as store-bought, so keeping it chilled is essential for freshness and food safety.
Enjoy: Use your homemade mayo as a spread, in dressings, or as a base for various sauces. The possibilities are endless!
