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 ↓
Scalloped Rice
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).
Butter an earthen baking dish.
Layer
Layer boiled rice in the bottom of the dish, then sprinkle with salt and pepper.
Add bits of butter on top of the rice.
Sprinkle a layer of cracker crumbs over the rice and season again.
Repeat layering rice and crumbs until the dish is two-thirds full, finishing with cracker crumbs.
Add chopped onion or parsley between layers if desired.
Bake
Pour broth, milk, or hot water over the layers just before baking.
Bake for 20 to 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled rice
- Forms the bulk of the dish and absorbs the liquid as it bakes.
- Cracker crumbs
- Add a toasted, crisp topping and help soak up moisture between rice layers.
- Butter
- Adds richness and helps the top and crumbs brown in the oven.
- Broth, milk, or hot water
- Supplies the moisture that softens the rice and crumbs during baking.
The step that matters
Pour the liquid just before baking. Adding liquid early lets the crumbs and rice soak it up unevenly before heat sets the dish, leaving it soggy or dry in patches.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (rice, pepper, butter, beef):
- Potatofits better
- Capsicumfits about as well
- Tomatofits about as well
- Onionthe original
Fit is the average pairing score against rice, pepper, butter, beef. Candidates are from the same food group and used in at least 100 recipes.
