What are five antonyms for biscuit?

Wouldn't have thought there'd be any. Antonym means "the opposite of"; what's the opposite of a biscuit? Not the same as an alternative, and doesn't mean "not a". Cakes, doughnuts, muffins, bagels and shortbread are not antonyms for biscuit; nor are albatross, coal, sausage, handbag and pterodactyl.
