Homemade mayonnaise can be delicious! You'll need egg yolks, oil, vinegar or lemon juice, and a bit of mustard. Whisk the yolks, slowly drizzle in oil while stirring briskly, then add vinegar, mustard, and seasonings to taste. Have you made mayonnaise before, or is this your first time trying? If you have any favorite flavors or variations, I'd love to hear about them!
