Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Tripe, Scotch Fashion
Ingredients
Directions
Stew the tripe until tender and let it cool.
Prepare veal forcemeat with finely minced onion and an egg.
Cut the thick part of the tripe into neat pieces, about 1.5 inches by 3 or 4 inches.
Spread some stuffing on each piece of tripe.
Roll the tripe pieces up neatly and skewer them to hold their shape.
Roll each piece in egg and then in fine breadcrumbs.
Fry in hot fat until golden brown.
