Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Make a Forcemeat Pie
Ingredients
Directions
Make a forcemeat by mincing calf's liver, ham, fresh pork, and eschalot. Pound in a mortar until smooth.
Add panard, egg, black pepper, and salt. Mix thoroughly and pass through a wire sieve, moistening with sherry if needed.
Cut game meat into neat pieces and break up bones. Place in a stewpan with calf’s foot, herbs, peppercorns, onion, mignonette pepper, salt, and mushroom ketchup. Cover with cold water.
Bring to a boil, skim, and simmer for 2-3 hours until a strong gravy forms. Strain and cool, removing any fat.
Butter a raised pie mold and line it with rolled pastry. Spread a layer of forcemeat on the bottom and sides.
Pack tightly with slices of ham or bacon and pieces of game. Season with salt and pepper. Add truffles, pistachio nuts, mushrooms, and pate de foie gras if desired.
Cover the top with bacon slices and a layer of forcemeat. Cut a piece of pastry to cover the top.
