Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare the potatoes
Wash and peel the potatoes.
Chop the potatoes finely and soak in cold water for 10 minutes.
Drain the potatoes and heat the butter or bacon fat in a frying pan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk of the dish, turning starchy and tender when cooked, then browning on the surface.
- Butter or bacon fat
- Conducts heat in the pan and adds richness and flavor while helping the potatoes brown.
- Vinegar
- Adds a little acidity that brightens the flavor of the potatoes and rich fat.
The step that matters
Increase the heat to brown the potatoes. Browning needs high heat and a dry surface. Cooking covered on low heat first softens the potatoes through, and a hot pan then creates the Maillard browning that gives crisp, golden flavor. Stirring too often prevents a crust from forming.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, vinegar):
- Capsicumfits better
- Mustardfits better
- Cabbagefits about as well
- Potatothe original
Fit is the average pairing score against butter, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
