Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Piquant Potatoes
Ingredients
Directions
Prepare
Boil the potatoes in their skins until tender.
Cut the bacon into small dice and place in a saucepan over medium heat until the fat has melted.
Make the sauce
Add the flour and a little sugar to the bacon, and cook until browned.
Add water to the saucepan to create a thick sauce and bring to a boil.
Slice the boiled potatoes thickly and add them to the sauce.
Bring the mixture to a boil again, then season with vinegar, salt, and sugar to taste.
Serve
Serve hot.

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 absorb the sharp, sweet sauce.
- Bacon
- Melts its fat to create the base for the sauce and adds savory, smoky flavor.
- Flour
- Thickens the bacon fat and drippings into a smooth sauce.
- Vinegar
- Adds acidity that gives the sauce its piquant, sharp flavor.
The step that matters
Cooking the flour in the bacon fat. Flour must cook in the fat until browned so it loses its raw taste and thickens properly. Adding water too early can leave lumps or a pasty flavor in the sauce.
Swap the potato
How well each one fits the dish's main ingredients (flour, vinegar, sugar):
- Mustardfits better
- Arrowrootfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against flour, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
