Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beet root
- Forms the main body of the pickle and provides its colour and earthy flavour.
- Spanish onions
- Adds sweetness and a sharp bite that softens as it sits in the brine.
- Vinegar
- Acidity that preserves the vegetables and gives the pickle its tang.
- Black pepper
- Adds a sharp, warm heat and aroma to the pickling liquid.
- Ginger
- Adds a fresh, spicy aroma that complements the beetroot.
The step that matters
Let the vinegar mixture cool before pouring. Pouring hot liquid over the beetroot and onions can soften them too much and cause the jar to crack. Cooling first keeps the vegetables firm and crisp while they pickle.
Swap the ginger
How well each one fits the dish's main ingredients (onion, vinegar, pepper):
- Garlicfits better
- Tarragonfits better
- Parsleyfits better
- Gingerthe original
Fit is the average pairing score against onion, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
