Why it works: Onion and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 18,226 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Chops, Stewed with Onion
Ingredients
Directions
Prepare the chops
Trim the fat from the loin chops and broil them for 2 minutes on each side.
Place the broiled chops on clean blotting paper.
Stew
In a saucepan, combine the sliced onions, salt, and butter.
Add the chops on top of the onions and cover the saucepan.
Stew gently until the onions are reduced to pulp, about 30 minutes.
Before serving, drizzle chili vinegar over the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Loin chops
- Provide the main protein, which is browned under the broiler before stewing.
- Spanish onions
- Break down into a soft pulp that forms the body of the sauce around the chops.
- Butter
- Adds richness and fat, helping the onions soften gently and carry flavor.
- Chili vinegar
- Adds acidity and sharp heat that cut through the rich butter and onion.
The step that matters
Stewing gently until the onions reach a pulp. Low, gentle heat with a covered pan lets the onions soften and release their moisture slowly. Rushing with high heat can scorch the butter and onions before they break down, leaving a dry, uneven base.

Fit is the average pairing score against butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
