Homemade mayonnaise is easier than you thought. It's fresh, tangy, and endlessly customizable -- you can flavor it however you please.
If the mayonnaise separates after the oil is added, the mixture has broken. To bring it to a creamy state, add an egg yolk and 1 teaspoon tepid water to a clean bowl, and slowly add the broken mayonnaise while whisking constantly. Then, whisk in 1/4 cup more oil.
