Preheat the oven to 375 degrees F.
Make the Biscuits: Using a sieve
over a bowl, sift
together the flour, baking powder, sugar, and salt. Repeat. Add the butter and shortening and, using your fingertips, mix until crumbly. Add the buttermilk
and mix with a wooden spoon until the dough just comes together. (Don't over mix!)
Transfer the dough to a lightly floured work surface and, using a rolling pin
, roll out to 1/2 to 3/4-inch thick rectangle. Using a 3 to 4-inch round cutter, punch
out biscuits and transfer them to a parchment paper-lined baking sheet. Gently press the dough
scraps into another rectangle and punch out more biscuits. Discard any scraps. Lightly dust
the tops of the biscuits with flour and bake until golden brown, about 12 to 15 minutes. Let the biscuits
cool slightly. (You'll only need 6 biscuits for the sandwiches, so serve the rest with soup
, spread with butter and jam
, or just freeze for another day.)
Make the Sandwiches: Preheat the broiler. Split 6 of the biscuits in half and spread the top halves with 1 tablespoon of tomato jam each.
Divide the ham
among the bottom halves of the biscuits and sprinkle the cheese
over the top.
Arrange the bottom halves a baking sheet and place under a broiler until the cheese melts. Cover with the biscuit tops and serve immediately.
