Food incest

When you put two foods that are made from the same base food together, some examples are:
Ketchup and salsa (Why?)
Hot dogs and pork ribs (Understandable, you can put a condom on a hotdog)
Rice and cereal (What is wrong with you?)

Person one: DUDE STOP PUTTING RICE IN YOUR CEREAL
Person two: Just try it, it tastes good I swear *-*
Person one: IT'S NOT EVEN COOKED, ANYWAYS THAT'S FOOD INCEST!
