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 ↓
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.
Prepare
Preheat the oven to 350°F (175°C).
Cut the peppers in half and remove all seeds.
Boil the beef until tender, then chop it finely.
Fill and bake
In a bowl, combine the chopped beef, beaten eggs, butter, cream, tomatoes, bread crumbs, onion, pepper seeds, celery seed, salt, and black pepper.
Fill the pepper halves with the mixture.
Sprinkle additional bread crumbs on top.
Bake until the peppers are brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the filling so it holds its shape when baked.
- Lean beef
- Provides the main protein and savory body of the filling.
- Bread crumbs
- Absorb moisture and add body to the stuffing.
- Cream
- Adds moisture and richness, keeping the filling tender.
- Tomatoes
- Add moisture and acidity that balance the rich beef.
- Butter
- Adds fat for richness and flavor in the filling.
The step that matters
Bake until the peppers are brown. The peppers must become tender and the filling must set through, but overbaking dries the beef and can toughen the eggs. Watch for browning and tender pepper walls rather than relying on time alone.
