Why it works: Potato and wheat match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 235 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Potatos Baked in Cups
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Mash the potatoes with butter and season with coarse sea salt and black pepper.
Butter some earthen tea cups and fill them with the prepared potato mixture.
Bake and brown
Bake in a 400°F (200°C) oven until golden.
Shape the potatoes in cups or bowls.
Brush with beaten egg.
Brown in the oven or before the fire.
If not using egg, dredge with wheat flour.
Baste with a little butter before baking.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Mashed starch forms the body of each cup and sets as it bakes.
- Butter
- Adds fat and richness and helps the surface brown.
- Beaten egg
- Gives the surface a glossy finish and helps it brown.
- Wheat flour
- Forms a dry coating that helps the surface brown when no egg is used.
The step that matters
Coating the surface before browning. Egg or flour on the outside helps the potato surface brown rather than stay pale. Without either, the cups can dry out or colour unevenly in the oven.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, egg, wheat, flour):
- Spinachfits better
- Chivefits about as well
- Asparagusfits about as well
- Potatothe original
Fit is the average pairing score against butter, pepper, egg, wheat, flour. Candidates are from the same food group and used in at least 100 recipes.
