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 ↓
Potato Salad with Bacon
Ingredients
Directions
Prepare the potatoes
Scrub the potatoes and boil them until tender.
Drain the potatoes, peel them while hot, cut into ¼‑inch slices, and season with salt and pepper.
Make the dressing
In a skillet, cook the bacon until light brown, adding 2 tablespoons of boiling water.
Stir in the vinegar, water, sugar, and flour mixed with ¼ cup of cold water. Cook the mixture until smooth.
Combine and serve
Pour the dressing over the sliced potatoes, add the onions, and mix thoroughly.
Before serving, pour ¼ cup of boiling water over the potatoes.

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 salad and absorb the dressing as they are sliced warm.
- Bacon
- Adds smoky fat and savory flavor to the dressing as it renders and browns.
- Vinegar
- Provides the sharp acidity that defines the tangy dressing.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Flour
- Thickens the dressing so it coats the potato slices instead of running off.
The step that matters
Cook the dressing until smooth. Flour must be fully cooked in the liquid to thicken evenly and lose its raw taste. Stirring while it heats prevents lumps, so the dressing coats the potatoes smoothly.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, vinegar, sugar, flour):
