Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beetroot Salad
Ingredients
Directions
Prepare the beets
Bake the red beets until tender, then let them cool.
Peel and slice the beets into thin rings, cutting large ones in half.
Assemble and season
Arrange the beet rings on a dish, placing half rings of Spanish onions between them.
Sprinkle with coarse sea salt and black pepper.
Add 2 tablespoons of vinegar for every ½ pound of beetroot.
Drizzle with a drop or two of chili vinegar if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red beets
- Provide the main body, sweetness and deep colour once baked until tender.
- Spanish onions
- Add a sharp, pungent aroma that adds contrast to the sweet beets.
- Vinegar
- Adds acidity that brightens the flavour and balances the beets' sweetness.
The step that matters
Bake the beets until fully tender. Beets must be cooked through to become soft and sweet. Underbaked beets stay firm and earthy, and the texture of the salad suffers.
