Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pickles (in the method)
- The main vegetable, whose firm, crisp slices give the finished pickles their texture.
- Salt
- Draws water out of the cucumber slices, firming them and seasoning the brine.
- Pulverized alum
- Helps the pickle slices stay firm and crisp during soaking.
- Vinegar
- Adds sharp acidity that preserves the pickles and gives them their tang.
- Onions
- Add sweetness and aroma as they soften in the jar.
- Hot red pepper
- Adds heat and colour to each jar.
The step that matters
Drain the water and rinse the pickles. Rinsing removes the salt and alum brine left on the slices, so the vinegar you add later sets the flavour and the pickles are not overly salty or harsh.
