Mix flour, sugar, salt and baking powder.
Cut in 1 cup shortening or so until texture is like ½ cornmeal, ½ pea.
Add milk gradually until well-moistened (might need more, up to ¾ cup, depending on humidity).
Gather into a ball (will look like not enough liquid); loose flour will disappear into it.
Pat about ¾ inch thick onto wax paper sprayed with Pam.
Drizzle top with melted butter; spread over dough.
Fold dough in half cross-ways; cut into diamonds and place cakes on greased, foil-lined baking pan or cookie sheet.
Bake at 450℉ (230℃). about 15 to 20 minutes.
