I always see condiments as something you might always keep on the meal table at dinner/supper.

Ketchup, tabasco, pepper, etc.

Mayonnaise? Nope.

A condiment is something you put on food that does not require refrigeration either before or after use. Ketchup, Mustard, BBQ sauce, and hot pepper sauces don’t require refrigeration.

The use of mayo as an ingredient is barely tolerable in the salads I mentioned, and strictly as a binder to hold the other parts together. It has no other purpose.
