Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Hot Bacon Potato Salad
Ingredients
Directions
Prepare the potatoes and bacon
Cook potatoes in boiling water until tender.
Peel, cut into slices, not too small, and place in mixing bowl.
Dice and fry 1/4 lb. bacon in a frying pan until almost crisp. Do not let burn.
Remove diced bacon and place into mixing bowl with other ingredients.
Make the dressing
Peel and dice onion and place into reserved bacon fat. Saute a few minutes.
Remove the sauteed diced onion with a slotted spoon and place into mixing bowl.
Into at least 2 Tbsp. bacon fat, cook 2 Tbsp. flour until smooth and bubbly, add 3 Tbsp. vinegar and 2 tsp. sugar, 1 tsp. salt, and enough water to make a medium sauce (about 1 cup or more).
Bring to a boil and cook until sauce is thickened.
Combine and serve
Pour over ingredients in mixing bowl, and toss and mix.
Taste, if needed add more salt.
Serve with hot baked ham or sausage. Good with a hot bean dish or salad.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red potatoes
- Provide the bulk of the salad and hold their shape when sliced and tossed.
- Bacon
- Adds smoky, savory flavor and fat that carries the dressing.
- Flour
- Thickens the bacon fat and vinegar mixture into a smooth sauce.
- Vinegar
- Adds acidity that brightens the sauce and balances the sugar and fat.
- Sugar
- Softens the sharpness of the vinegar for a balanced sweet-sour sauce.
- Onion
- Contributes sharp aroma and flavor after being softened in bacon fat.
The step that matters
Thickening the sauce. Flour must cook in the bacon fat until smooth and bubbly before liquid is added, otherwise it stays lumpy and tastes raw. The sauce then needs a full boil so the starch swells and thickens it properly.
Swap the onion
How well each one fits the dish's main ingredients (potato, vinegar, flour, sugar):
