Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Baked Potato Dice
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 the potatoes
Peel and cut the potatoes into dice or strips half an inch thick.
Soak the potatoes in cold water for 30 minutes.
Drain and wipe the potatoes, then coat them in melted butter.
Bake and serve
Pour the remaining butter into a baking dish and arrange the potatoes irregularly.
Sprinkle with salt, pepper, lemon juice, and onion juice.
Cover the dish and bake at 350°F (175°C) for 45 minutes or until tender.
Serve dry on a hot dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy body of the dish, becoming tender and fluffy when baked.
- Butter
- Adds richness and moisture, helping the potato pieces brown and carry seasoning.
The step that matters
Drain and wipe the potatoes before coating them in butter. Surface water left on the cubes dilutes the butter and steams the potatoes instead of letting the fat coat them evenly, so drying them well helps the butter cling and the surfaces brown.
Swap the lemon

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