Why it works: Cider and vinegar are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,431 recipes. Both carry 4-ethyl-2-methoxyphenol, which smells smoky, clove. The science ↓
Pickled Beets
Ingredients
Directions
Prepare the pickling liquid
Heat the cloves in cider vinegar over medium heat for 30 minutes without boiling, then let cool.
Prepare the vegetables
Slice the boiled and skinned beets and let them cool.
Thinly slice the small white onions.
Pack and pickle
In a glass or stone jar, layer beets, onion slices, a spoonful of the vinegar and cloves, and a pinch of salt.
Repeat the layering until the jar is almost full, then fill with cold cider vinegar.
Let the pickles sit for 24 hours before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider vinegar
- Provides the acidity that preserves the beets and gives the pickle its sharp flavour.
- Small dark red beets
- Supply the main body, earthy sweetness and deep red colour of the pickle.
- Small white onions
- Add sharp, pungent flavour that mellows as the onions soak in the vinegar.
- Cloves
- Infuse the vinegar with warm, aromatic spice.
The step that matters
Keep the vinegar from boiling when infusing the cloves. Boiling would drive off volatile aromatic compounds from the cloves and make the vinegar harsher, so gentle heat is used to extract flavour without losing it.
Swap the onion
How well each one fits the dish's main ingredients (clove, cider, vinegar):
- Mustardfits better
- Shallotfits better
- Cucumberfits better
- Onionthe original
Fit is the average pairing score against clove, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
