To make sure your Yorkshire pudding sandwiches are heated through, prepare your fillings just before cooking so they’re still warm when you assemble the sandwiches.
Lay out the Yorkshire puddings. Spread cranberry sauce over half of each pudding, then spoon the mashed potato on top. Add the pigs in blankets and tear over the stuffing balls. Finish with slices of Brie.
Heat your panini press. Alternatively, use a griddle pan and turn the sandwiches halfway through cooking. Take a Yorkshire pudding and carefully fold it over the fillings so everything is fully enclosed. Heat until the outside is crispy and the cheese has melted. Repeat with the second pudding. Meanwhile, warm the gravy and serve it drizzled generously over the sandwiches.
