Mice take a lot of preparing - they're a delicacy, though the foetuses can be eaten raw in lieu of caviar by the poorer classes who aspire to impress their guests with something truly exotic. What do mice taste like? Depends what you feed them on; a chocolate-fed mouse is going to taste different from one fed on grain, but mice have a very sweet tooth so chocolate's best I'd say. Cheese? No chance, but marinaded in milk overnight and shallow fried in butter a young mouse makes a crunchy breakfast treat.
