These delicate hors d'oeuvre "cups" of grated cheese are browned in a hot skillet, then shaped and cooled over inverted glasses.
Heat a nonstick 12-inch skillet over medium-low heat. Combine cheese and flour in a medium bowl. Place 3 to 4 small overturned glasses next to work area.
When skillet is hot, sprinkle 3 tablespoons of the cheese mixture into a thin round, about 4 inches wide; repeat, making three more rounds. Cook until cheese is golden brown on bottom, 1 1/2 to 2 minutes.
Carefully, using tongs and a flexible spatula, loosen the edges of rounds, lift up, and turn over. Let rounds cook about 10 seconds more; remove from the pan, and place on an overturned glass or inside a small bowl. Repeat with remaining cheese mixture. Let cool until firm, about 1 minute. Transfer to a wire rack to fully cool; serve.
When you place the hot rounds of cheese onto inverted drinking glasses the edges drape over the edge and form a crisp, cup-shaped cracker.
