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 ↓
Soy-bean Meat Loaf
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
Preheat the oven to 350°F (175°C).
Mix and shape
In a bowl, combine chopped meat, chopped onion, soy‑bean mush, dried celery leaves, mashed potatoes, and salt, and mix well until all ingredients are combined.
Shape the mixture into a loaf or small cakes.
Bake
Place in a baking dish and bake for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soy-bean mush
- Provides bulk and protein-rich body, holding the loaf together with a soft, moist texture.
- Mashed potatoes
- Adds moisture and binding starch, helping the loaf stay tender and hold its shape.
- Chopped meat
- Forms the main body of the loaf and adds savory flavor and fat for richness.
- Chopped onion
- Adds moisture and aromatic flavor that deepens the savory taste of the loaf.
The step that matters
Mix until all ingredients are combined. Thorough mixing distributes the binders and moisture evenly, so the loaf holds together when sliced and bakes with a consistent texture rather than crumbling in spots.
Swap the celery
How well each one fits the dish's main ingredients (meat, onion, potato):
- Garlicfits better
- Thymefits better
- Celerythe original
- Parsleyfits about as well
Fit is the average pairing score against meat, onion, potato. Candidates are from the same food group and used in at least 100 recipes.
