Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Forms the crisp, firm bulk of the pickle after salting.
- Mustard
- Supplies the sharp, pungent flavor that defines the pickle.
- Flour
- Thickens the cooking liquid so it clings to the vegetables.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Turmeric powder
- Gives the pickle its yellow color and a earthy aroma.
- Coarse sea salt
- Draws water out of the vegetables, leaving them crisper.
The step that matters
Stirring in the flour mixed in cold vinegar. Flour added dry or to hot liquid clumps. Suspending it in cold vinegar first lets the starch spread evenly, so it thickens smoothly when the mixture heats.
