Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers: Form the pickle itself; their firm texture is kept through the brining and soaking.
Brine: Salt draws water out of the cucumbers and firms their texture before pickling.
Cider vinegar: Provides the acidity that preserves the pickles and gives their sharp flavor.
Brown sugar: Balances the sharpness of the vinegar with sweetness and depth.
Alum: Helps the cucumbers stay firm and crisp during long storage.

The step that matters

Draining and drying the cucumbers before the spiced pour. Any water left on the cucumbers dilutes the hot vinegar mixture and weakens its acidity, which can let the pickles soften or spoil. Thorough drying keeps the preserving liquid strong.
