Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Blanch the pork in boiling water for 5 minutes, then drain.
Cook
In a 2-liter pot, melt the butter and sauté the pork for 5 minutes.

Add the peas and the whole onion, then pour in the water.
Cover and simmer for 30 minutes.
Taste for salt, remove the onion, skim off excess fat, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork belly
- Provides fat and rich meaty flavour that renders into the dish.
- Butter
- Adds fat for sautéing the pork and a rounded, savoury richness.
- Flour
- Toasted in the fat, it thickens the cooking liquid into a looser sauce.
- Peas
- Form the main body of the dish and provide sweetness and texture.
The step that matters
Skim off excess fat. Pork belly releases a lot of fat as it cooks. Skimming it before serving keeps the dish from tasting greasy and gives the liquid a cleaner, lighter texture.
Swap the peas
How well each one fits the dish's main ingredients (pork, butter, flour, onion):
- Sesamefits better
- Almondfits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against pork, butter, flour, onion. Candidates are from the same food group and used in at least 100 recipes.
