Biscuits

Everybody loves a good cookie

To most of the rest of the English-speaking world, a biscuit is what Americans would refer to as either a cookie or a cracker. Biscuits can be sweet (shortbread) or savory. They're baked in the oven, and they're crisp, not chewy. That's why the biscuit challenges on The Great British Baking Show usually include both sweet biscuits and savory ones.

What about chewy cookies, like chocolate chip or snickerdoodle? These aren't nearly as common in the UK as they are in the US, but when they're made there, they're still called cookies.
