Aioli and mayo are both creamy sauces made by emulsifying oil with a few additional ingredients. True aioli is simply olive oil and garlic while mayo adds egg yolks and other seasonings. However, aioli is sometimes made by modifying a mayonnaise recipe by adding garlic, lemon or other flavorful additions. These two sauces boast different flavor palates. Aioli can be used when dipping vegetables or as a sauce for shellfish, whereas mayo is often used as a spread or a base for pasta/potato salads. If you’re looking for aioli or mayo to add to your meal, try making some homemade aioli or vegan herb mayo as a side.
