Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the main bulk and tart flavor of the pickle.
- Chili pepper
- Adds heat and pungency to the pickle.
- Onions
- Add sweetness and savory depth as they soften during cooking.
- Cabbage
- Contributes bulk and a crisp-tender texture after salting and cooking.
- Mustard seed
- Adds a sharp, pungent flavor that deepens during cooking.
- Vinegar
- Provides acidity that preserves the vegetables and gives the pickle its tang.
The step that matters
Salting and draining overnight. Salt draws water out of the chopped vegetables by osmosis, so draining off the liquid concentrates flavor and keeps the pickle from becoming watery. Skipping or shortening this rest leaves excess moisture in the final pickle.

How well each one fits the dish's main ingredients (pepper, onion, cabbage, celery, horseradish, mustard, vinegar):
- Broccolifits better
