Why it works: Tomato and potato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,798 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Hash
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Grind or chop the left-over meat.
Mix the meat with gravy, tomato sauce, or white sauce.
Butter a baking dish and line it with mashed potatoes or rice.
Place the meat mixture into the dish.
Bake and serve
Set the dish in a pan of hot water.
Heat in a moderate oven at 350°F (175°C) until warmed through.
Serve directly from the baking dish.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sauce and butter barely smell alike, yet cooks put them together in 15,338 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Left-over meat
- Forms the main filling and provides the savory flavor of the hash.
- Gravy
- Adds moisture and savory flavor so the meat does not dry out while baking.
- Tomato sauce
- Adds acidity and sweetness, and moisture to the meat mixture.
- White sauce
- Adds richness and moisture, binding the meat into a creamy filling.
- Mashed potatoes or rice
- Forms the base layer that holds the filling and absorbs its moisture.
- Butter
- Adds fat and flavor and helps keep the base from sticking to the dish.
