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

What each ingredient does

White walnuts
Form the main body of the pickle, taking on flavour as they soak in the spiced vinegar.
Vinegar
Acidifies and preserves the walnuts while carrying the spice flavours into them.
Sugar
Balances the sharpness of the vinegar with sweetness.
Garlic or onions
Adds pungent aroma and savoury depth to the pickling liquid.

The step that matters

Soaking the walnuts in salt water. Salt draws out bitterness and tannins from the walnut hulls and rinds; a weak or short soak can leave the pickle harsh, so the full two weeks in strong brine matters.

Swap the walnut

How well each one fits the dish's main ingredients (vinegar, garlic, clove, allspice, pepper, sugar):
