Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 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
Preheat the oven to 350°F (175°C).
Assemble and bake
In a bowl, mix the chopped meat, onion, potato, salt, and pepper.
Add enough water to moisten the mixture.
Transfer the mixture to a buttered baking dish.
Cover the top with buttered crumbs.
Bake until the crumbs are brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked meat
- Forms the bulk of the dish and provides its savory, substantial body.
- Onion
- Adds aroma and a mild sweetness as it softens during baking.
- Cooked potato
- Adds starch and body, helping the hash hold together and feel hearty.
- Buttered crumbs
- Browns in the oven to give a golden, crisp topping.
The step that matters
Moistening the mixture. Adding water gradually, only until the mixture is damp, keeps the hash moist without making it soggy. Too much water steams the mixture and dilutes its flavor.
Swap the onion
How well each one fits the dish's main ingredients (meat, potato, pepper):
- Capsicumfits better
- Carrotfits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against meat, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
