Why it works: Lettuce and tomato are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,655 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
Fry the bacon, lettuce, tomato, and onion together.
Remove the seeds from the peppers.
Stuff and bake
Stuff the peppers with the mixture.
Place a small piece of butter on each pepper.
Bake in a moderate oven at 350°F (175°C) until cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon
- Renders fat that carries flavor and browns the filling as it fries.
- Lettuce
- Wilts when cooked, releasing moisture and adding a soft, leafy texture to the filling.
- Tomato
- Adds moisture and a bright acidity that balances the rich bacon.
- Onion
- Softens and turns sweeter as it fries, adding aroma to the filling.
- Peppers
- Form the edible shell that holds the filling and soften as they bake.
- Butter
- Adds richness and fat that helps the tops brown in the oven.
The step that matters
Bake until cooked through. Raw pepper walls stay firm and crisp, so the peppers need enough oven time for heat to soften them while the filling cooks through.
Swap the lettuce
How well each one fits the dish's main ingredients (tomato, onion, pepper, butter):
- Capsicumfits better
- Potatofits better
- Okrafits better
- Lettucethe original
Fit is the average pairing score against tomato, onion, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
