If you’ve stood in the grocery store wondering whether mayonnaise and aioli are basically the same thing, you’re not alone. Here’s what I have learned cooking with both.
Quick Answer
Mayo is the neutral spread. Aioli is the upgraded garlicky version. For sandwiches and dipping fries, aioli is the better choice. For salads and crowd-pleasing dishes, mayo.
