Why it works: Onion and potato 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 Potato Salad
Ingredients
Directions
Make the dressing
Shred the bacon and cook in a hot frying pan until crisp.
Remove the bacon and sauté the chopped onion in the bacon fat until golden brown.
Measure the fat, then add half the amount of vinegar, salt if needed, and cayenne pepper.
Add half the amount of hot chicken stock or water and mix well.
Assemble and serve
Remove the skins from the hot boiled potatoes and slice them into the hot mixture to absorb the liquid.
Add the bacon shreds and toss everything lightly until well mixed.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon
- Adds savory fat and crisp pieces that flavour the warm dressing.
- Onion
- Browns in the bacon fat, adding sweetness and savory depth to the dressing.
- Vinegar
- Adds acidity that sharpens the dressing and balances the fat.
- Hot boiled potatoes
- Form the body of the salad and absorb the warm dressing as they are sliced in.
- Chicken stock or water
- Adds liquid that the hot potatoes absorb, carrying flavour through the salad.
The step that matters
Slice the potatoes into the hot mixture while they are still hot. Warm potatoes are porous and absorb the dressing well, while cold potatoes stay firm and resist it, leaving the salad bland and dry.
