Why it works: Potato and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 8,303 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Peel the potatoes and cut them into cork shapes, about 3 inches long.
Simmer

Simmer gently until the potatoes are tender.
Finish and serve
Strain the sauce and pour it over the potatoes.
Drizzle melted butter on top and serve.

Sauce and butter share little aroma chemistry, yet 15,317 recipes mention both: they likely 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
- Form the bulk of the dish and turn tender and soft during simmering.
- Spanish sauce
- Provides the rich, savoury body of the sauce that coats the potatoes.
- Sherry
- Adds acidity and aromatic depth to the simmering sauce.
- Melted butter
- Adds fat and a glossy finish to the finished dish.
The step that matters
Simmer gently until the potatoes are tender. Boiling vigorously can break the potato pieces apart and cloud the sauce. A gentle simmer lets the potatoes cook through while keeping their shape and the sauce smooth.
