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 ↓
Dried Peas
Ingredients
Directions
Prepare the peas
Soak the dried peas overnight in water.
Cook the peas in fresh water until tender, similar to white dried beans.
Pass the cooked peas through a sieve.
Season and serve
Season the peas with coarse sea salt and beef drippings.
In a skillet, brown the chopped onion in butter.
Pour the browned onion gravy over the seasoned peas before serving.
Serve the peas thickened, optionally with sauerkraut.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried peas
- Their starch thickens as they cook and gives the sieved purée its body.
- Butter
- Carries the onion's flavour and helps it brown in the skillet.
- Onion
- Browning develops sweetness and savoury aroma for the gravy.
- Beef drippings
- Adds fat and savoury meaty flavour that carries through the peas.
The step that matters
Cook the peas until fully tender before sieving. Starch in peas only gelatinises fully when cooked long enough, so undercooked peas stay grainy and will not pass through a sieve into a smooth, thickened purée.
Swap the peas
How well each one fits the dish's main ingredients (beef, onion, butter):
- Sesamefits better
- Peanutfits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against beef, onion, butter. Candidates are from the same food group and used in at least 100 recipes.
