Why it works: Mustard and potato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,340 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Hot Potato Salad
Ingredients
Directions
Prepare the potatoes and bacon
Boil five or six large potatoes until cooked, then cut them into thin slices while hot.
Fry thin slices of bacon and cut into small pieces until there is a half cupful of bacon pieces.
Pour off the bacon fat from the frying pan, leaving two tablespoonfuls of fat.
Make the sauce
Stir a teaspoon of flour into the hot fat, along with a quarter teaspoon of mustard, an eighth teaspoon of pepper, and a quarter teaspoon of salt.
Stir the mixture to a smooth paste.
Stir in a half cup of vinegar.
Let the mixture come to a boil.
Combine and serve
Mix the hot potatoes with the sauce.
Serve while hot.

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 salad, absorbing the warm dressing as they are mixed in.
- Bacon (in the method)
- Adds savory, smoky flavor and crisp pieces, and its fat carries the sauce.
- Flour (in the method)
- Thickens the hot bacon fat into a smooth, cohesive sauce.
- Vinegar
- Adds acidity that brightens the sauce and balances the rich bacon fat.
The step that matters
Stir the flour into the hot fat to a smooth paste. Flour must be fully worked into the hot fat so it cooks briefly and thickens evenly; adding it lumpy or to cold fat leaves clumps and a raw floury taste.
