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

What each ingredient does

Green tomatoes
Provide the bulk of the pickle and release moisture that the salt draws out.
Coarse sea salt
Draws water out of the vegetables, firming them and preserving them before pickling.
White mustard seed
Adds pungent flavor and sharpness that carries through the vinegar.
Ground mustard
Adds sharp, pungent mustard flavor and helps thicken the pickle.
Vinegar
Acidifies the pickle, preserving it and giving it its tangy flavor.

The step that matters

Squeezing out the brine. Salted vegetables release a lot of liquid. If the brine is not squeezed out well, the pickle stays watery and can dilute the vinegar, weakening both texture and preservation.

Swap the tomato
