Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young onions
- Provide the main vegetable bulk and a sharp, savoury flavour once pickled.
- Sour apples
- Add tartness and crisp texture that balances the salt and spice.
- Fresh cucumbers
- Contribute crunch and fresh, watery bulk to the pickle.
- Soy sauce
- Adds savoury depth and salty umami to the liquid.
- Vinegar
- Acidifies and preserves the vegetables, giving the pickle its sour bite.
The step that matters
Fill the jar with vinegar and cover it tightly. The vinegar must fully cover the sliced vegetables so none are exposed to air, which could let spoilage organisms grow. A tight cover keeps the jar sealed while the flavours develop.
Swap the apple
How well each one fits the dish's main ingredients (onion, cucumber, pepper, sherry, sauce, vinegar):
- Avocadofits better
