Why it works: Potato and onion 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 Meat Loaf with Peas
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the binder
Soak the bread in cold water for a few minutes, then press it between your hands until dry.
Mash the potatoes using a fruit press or potato ricer.
Combine the dry bread with the mashed potatoes, drippings, and onions.
Cook the mixture until heated through.
Mix and bake
Add the ground meat, seasoning, and parsley; mix well.
Transfer the mixture to a small well-greased pan and bake at 350°F (175°C) for 30 minutes.
Serve
Serve on a plate with small boiled potatoes around it, covered with white sauce and green peas.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Soaked and squeezed bread absorbs and holds moisture, helping bind the loaf together.
- Cold boiled potatoes
- Mashed potatoes add starch and moisture, helping the loaf hold together and stay tender.
- Canned roast beef
- The meat forms the main body of the loaf, providing savory flavor and a firm texture.
- Drippings or oil
- Fat coats the mixture, adding richness and moisture and keeping the loaf tender.
The step that matters
Squeeze the soaked bread dry. Excess water dilutes the binding starch and makes the loaf loose and soggy. Dry bread and potatoes give a firm mixture that holds its shape and sets as it bakes.
Swap the parsley
How well each one fits the dish's main ingredients (beef, bread, potato, onion):
- Garlicfits better

- Celeryfits about as well
- Parsleythe original
Fit is the average pairing score against beef, bread, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
