Prepare the tomatoes

Cover the tomatoes with cold vinegar and seal the jar.
Store the jar in a cool, dark place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body of the pickle, softening and absorbing the brine and vinegar flavours.
- Mustard seed
- Adds pungent, sharp flavour that develops as the pickle matures.
- Red pepper pods
- Add heat and a fresh, sharp bite to the pickled tomatoes.
- Cold vinegar
- Acidifies the jar, preserving the tomatoes and giving the pickle its tang.
The step that matters
Soaking the tomatoes in salted water. Salt must fully dissolve so the brine is strong enough to draw water out of the tomatoes and firm their flesh. Weak brine can let the tomatoes soften or spoil during the week-long soak.
Swap the tomato
How well each one fits the dish's main ingredients (mustard, pepper, vinegar):
- Horseradishfits better
