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

What each ingredient does

Green tomatoes
Supply the bulk of the pickle and, after salting, release juice that is drained off before pickling.
Ground mustard
Gives the pickling liquid its sharp, pungent mustard flavour.
Brown sugar
Adds sweetness that balances the sharpness of the vinegar and mustard.
Flour
Thickens the hot vinegar mixture so it coats the vegetables rather than running off.
Vinegar
Acidic base that preserves the vegetables and carries the mustard and sugar flavours.

The step that matters

Mixing the flour and mustard smoothly with cold vinegar before adding it to the hot vinegar. Flour and ground mustard clump when added dry or to hot liquid. Blending them into cold vinegar first keeps the particles separate, so the mixture thickens evenly once heated and cooked through.

Swap the onion
