…at least sometimes I do. And it’s for your own good.
There are lots of ingredients out there that you’d never want to eat on their own, or with them simply perched on top of your food. These things get mixed in–ingredients like baking soda, raw eggs (usually), dried chili peppers and worchestershire sauce.
You wouldn’t eat beef or chicken bouillon cubes on their own (unless you’re a freak!). So why would anyone set a whole anchovy on top of a pizza and eat it just like that? It needs to be chopped finely and mixed into the sauce or distributed judiciously, with other ingredients layered to accompany it. I’ve met few people who like anchovies, but I think it’s because they don’t know to do with them. Anchovies are ingredients and thus to be used, not foods to be consumed whole, unless you’re one of those rare people with a sodium deficiency.
So if you come to my house and I feed you the best spaghetti sauce of your life, it will be because there are ingredients in it that you never thought to put in there yourself. They’re probably ingredients you don’t even think you like. You’ll be surprised by how much you do like them–when they’re used properly.
