Mayonnaise can be made simply by emulsifying oil into egg yolks. It's super easy to make if you want, and it's easy to modify by adding spices or seasonings. You don't eat it by itself, but it's fantastic for use in baking, mashed potatoes, sandwiches, sauces, and dips.
Mayo is primarily an ingredient for use on something else. You would never eat flour by itself, just like you'd never eat straight mayo by itself.
