Why it works: Rice and chicken are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 4,769 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓
Green Peppers Au Gratin
Ingredients
Directions
Prepare the peppers
Cut the stem end from the peppers.
Remove the seeds with a penknife and small spoon.
Soak the peppers in cold water for 30 minutes.
Fill and sauce
Mix the rice, minced chicken, salt, butter, and enough tomato juice to moisten.
Fill the peppers with the mixture, heaping it up.
Stand the filled peppers upright in a deep dish.
Fill the gaps with the remaining mixture.
Pour tomato sauce thickened with drawn butter into the dish.
Bake and serve
Sift fine bread crumbs over the top.
Dot the crumbs with butter.
Cover the dish and bake for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peppers
- Hollowed shells that hold the filling and soften as they bake.
- Cold boiled rice
- Bulks out the filling and absorbs moisture so it stays tender rather than wet.
- Cold minced chicken
- Provides the savoury protein that forms the body of the filling.
- Tomato juice
- Moistens the filling so the rice and chicken hold together.
- Tomato sauce
- Forms a moist, tangy sauce in the dish that surrounds the peppers as they cook.
- Fine bread crumbs
- Form a crisp topping that browns when the dish is uncovered.
The step that matters
Uncover to brown. The dish is covered for most of baking, which traps steam and keeps the peppers and crumbs pale and soft. Uncovering lets moisture escape and surface sugars and starches brown, so the topping needs watching at the end.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, rice, chicken, butter, sauce, bread):
- Capsicumfits about as well
- Tomatothe original
- Potatofits less well
- Asparagusfits less well
Fit is the average pairing score against pepper, rice, chicken, butter, sauce, bread. Candidates are from the same food group and used in at least 100 recipes.
