FOIL HOLDERS: To make foil holders cut 6-10 pieces of foil into 4x8 inch (for sandwich rolls) or 4x10 inch (for hamburger buns) strips. Fold each strip in half to make them 4x4 or 4x5 inches. Mold the foil strips around the bottom of a 3 inch diameter mug (for sandwich rolls) or a 4 inch diameter bowl (for hamburger buns) Place the holders onto a large baking sheet and lightly spray them with cooking spray to prevent the dough from sticking. Fill the holders as directed above.
