Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Stuffed Onions
Ingredients
Directions
Prepare the onions
Peel the onions and place them in a saucepan of boiling water.
Boil until soft enough to remove the middle part; small onions take about 1 hour, large ones 1.5 to 2 hours.
Make the filling
Mince the cooked meat, ham, bacon, or fowl together.
Add the bread crumbs, seasoning, and chopped onion pieces.
Bind the mixture with a little milk or stock.
Fill the onion shells with the mixture.
Cook and serve
Place them in the saucepan and pour in enough hot stock to half cover them.
Simmer for a little more than half an hour.
Once cooked, remove the onions and place them on a dish.
Thicken the gravy with 2 teaspoons of flour mixed with a little cold water and browning.
Pour the gravy around the onions and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions (in the method)
- Form the edible shells that hold the filling and soften during boiling.
- Meat remnants
- Provide the savory body of the filling.
- Bread crumbs
- Absorb liquid and help bind the filling so it holds together.
- Flour (in the method)
- Thickens the gravy so it coats the onions instead of running off.
The step that matters
Remove the middle part of the onions while they are soft. Onions must be cooked enough to scoop out without tearing, but not so long that the shells collapse. Undercooked shells crack when cut, and overcooked ones lose their shape and hold less filling.
Swap the parsley
How well each one fits the dish's main ingredients (meat, pepper, bread, milk):

- Parsleythe original
Fit is the average pairing score against meat, pepper, bread, milk. Candidates are from the same food group and used in at least 100 recipes.
