Why it works: Rice and lemon are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,366 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓
Macaroni and Rice
Ingredients
Directions
Prepare
Fill a large stew-pan with water, leaving room for boiling, and add salt and lemon juice.
Sift and rinse the rice to clean it.
Keep a jug of cold water nearby.
Cook the rice
Add the rice to the boiling water.
Stir gently with a wooden spoon.
After 10 to 12 minutes, test the rice by pinching a few grains.
Add the cold water to stop the cooking.
Drain and dry
Drain the rice completely.
Return the drained rice to the hot stew-pan.
Shake the pan well.
Cover the pan with a clean napkin to dry for 8 to 10 minutes.
Add butter to detach any grains stuck to the bottom.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Provides the starch and bulk that make up the dish, cooking into separate grains.
- Butter
- Adds fat and richness and helps loosen grains stuck to the pan.
- Lemon juice
- Adds acidity that brightens flavour and helps the grains stay white.
The step that matters
Testing the rice before draining. Rice keeps cooking in its own heat after it leaves the water, so a grain pinched too late turns soft and mushy. Testing at the first sign of tenderness and then cooling the rice with cold water stops the cooking at the right point.

Fit is the average pairing score against rice, butter. Candidates are from the same food group and used in at least 100 recipes.
