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 ↓
Potato Fricasse
Ingredients
Directions
In a stewpan, brown the sliced salt pork.
Add the sliced onion and a little cold water; cook for a few minutes.
Add the cut-up potatoes and black pepper.
Cover with cold water and bring to a hard boil for 2 hours.
If the mixture is not thick enough half an hour before serving, remove the cover and boil until it thickens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat for browning and flavours the whole pot.
- Potatoes
- Break down as they cook and thicken the liquid into a starchy sauce.
- Onion
- Softens and adds sweetness and savoury depth to the base.
The step that matters
Boiling the mixture uncovered to thicken. Potato starch thickens the liquid only as water evaporates. Removing the cover at the right time lets excess moisture reduce, so the fricassée thickens instead of staying thin.
