Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Italian Macaroni Pie
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut the beef or mutton into thin slices.
Peel and slice the onion thinly.
Slice the tomatoes.
Boil the macaroni in slightly salted water until tender, then cool and drain it.
Cut the macaroni into small pieces.
Assemble
Line a buttered baking dish with macaroni.
Arrange the meat, onion, and tomato slices in layers in the baking dish.
Season with salt, pepper, and nutmeg, then pour over a little stock.
Cover the top with macaroni, then sprinkle with breadcrumbs and grated cheese.
Bake
Bake for about 20 minutes at 400°F (200°C).
