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 ↓
Meat Stuffed Peppers
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Mix the ground beef, tomatoes, onions, Tabasco sauce, salt, white pepper, bread crumbs, and beaten egg together in a bowl.
Cut off the stem end of the green peppers and remove the seeds.
Stuff and bake
Stuff the pepper with the meat mixture and replace the stem end, securing it with a toothpick.
Place the stuffed peppers in a casserole or baking dish.
Cover the dish.
Bake until the peppers are tender, about 30-40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground lean beef
- Forms the main filling and provides savory flavor and body.
- Bread or cracker crumbs
- Absorb liquid and help hold the filling together with the egg.
- Egg
- Binds the filling so it holds its shape when baked.
- Sieved tomatoes
- Add moisture and acidity to the filling.
- Onions
- Add aroma and sweetness as they soften in the filling.
The step that matters
Covering the dish before baking. Covering traps steam so the peppers become tender and the meat cooks through evenly, while the filling stays moist rather than drying out in the oven.
Swap the white pepper
How well each one fits the dish's main ingredients (beef, tomato, onion, sauce, bread, egg):
- Garlicfits better
- Capersfits better
- Celeryfits better
- White pepperthe original
Fit is the average pairing score against beef, tomato, onion, sauce, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
