What condiments are staples in your fridge? I always have mayonnaise(atleast 2 types, original and some spicy version) and mustard. Three kinds of mustard, grainy, some fancy local version and Dijon mustard. ALWAYS Dijon Mustard! I love the smoothness of it and spice kick in the nose that is beautifully balanced. 

Mustard and Mayo - together, and just the two of them, they make the best spreads for sandwiches!
