Why it works: Apple and butter are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 8,706 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Casserole of Sausage, Spaghetti and Apple
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).
Grease the bottom of a baking dish with butter.
Assemble and bake
Layer the cooked spaghetti in the bottom of the dish.
Add a layer of seasoned sausage meat on top of the spaghetti.
Spread a thick layer of slightly sweetened chopped apple over the sausage.
Top with buttered crumbs.
Bake until the apple and sausage are cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spaghetti
- Forms the base layer that holds the casserole together and gives it bulk.
- Sausage meat
- Supplies the savory, fatty flavor that carries through the whole casserole.
- Chopped apple
- Adds moisture and a mild sweetness that balances the seasoned sausage.
- Buttered crumbs
- Form the topping, where butter helps the crumbs brown in the oven.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, apple, butter):
- Potatofits better
- Capsicumfits about as well
- Shallotfits about as well
- Onionthe original
