Hamburgers and Focaccia
I like focaccia. I don't even mind sandwiches served on it, though good sandwich bread is underappreciated. Hamburgers should never be served on focaccia. Focaccia is too delicate to stand up to a hamburger. A properly cooked (still juicy and pink) and dressed hamburger will turn a piece of focaccia into mush. I've gone to several higher-end restaurants that offer a $9-$12 burger on the menu, and they all seem to put them on focaccia. Stop it! If you can't stand an ordinary hamburger bun, then make one! Homemade hamburger buns can be fabulous.
