Ingredients
Directions
Prepare the base
Rub mustard into a smooth paste with salad oil and vinegar.

Pour in vinegar and brown sugar.
Set the jar in a pot of cold water over the stove.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Best mustard
- Forms the smooth paste base and provides the pungent mustard flavor.
- Cabbage
- Adds bulk and crisp texture that holds up through the long simmer.
- Cucumbers
- Contribute crisp texture and fresh bulk to the finished pickle.
- Brown sugar
- Balances the sharp vinegar with sweetness and adds depth to the sauce.
- Vinegar
- Provides the acidity that preserves the pickle and sharpens the flavor.
- White mustard seed
- Adds pungent, nutty bite and texture to the thickened sauce.
The step that matters
Simmering the sauce for three hours. Long, gentle simmering with occasional stirring lets the mustard paste and spices blend and mellow while the vegetables soften, and prevents the bottom from scorching as the liquid reduces.
Swap the white pepper
