Food for an Alice in Wonderland RPG? Answered

Cookies with "EAT ME" written on them in icing
Bread-and-butterflies (buttered bread cut into a butterfly shape)
Stuffed mushrooms (stuffed with oysters, maybe?)
Miniature sandwiches shaped like hearts, diamonds, spades and clubs
Shots of mezcal (an agave worm is actually a caterpillar, ya know)
Cheshire cheese
Heart-shaped strawberry tarts

Angels and  Devils on horseback, mock-turtle soup (or mock mock-turtle soup if you don't fancy the offal) with crusty rolls and ginger beer to drink.

For later on, tea of course, bread, butter and orange marmalade (Frank Coopers Vintage Oxford Marmalade is the best around) and little iced cakes with cherries on top.

Puns are the only food you need!

Turtle Soup of course

Oysters, or those chocolates that look like oysters.

Hot tea, ginger snaps and chocolate covered 'shrooms. (Take some chocolate (milk chocolate works best) and melt it in a double boiler or microwave. Allow it to cool as much as it can without getting hard, dip the mushrooms and harden in the freezer.)
