Gastronomic Economics on the First Day of Class

Today is the first day of class.

As any of you who have taken economics classes know, it is common to draw graphs where the x-axis is the amount of one good you consume and the y-axis is the amount of another good you consume. (The more you consume of one good the less money you have left over for the other.)

This gastronomic economists is seeking suggestions about pairs of gastronomically related goods. "Beer" and "pizza" is the standard pair, but I think we can be more creative. (Guns and butter is also common but guns are unrelated to food; my first class used drugs and everything else as the two goods.) Please leave comments with creative food-related goods pairs of goods I can use in class. Particularly welcome would be creative food-related pairs that are compliments or substitutes. Examples of superior, normal, inferior, and Giffen food-related goods are also welcome.
