Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green bell peppers
- Their whole shells hold the stuffing and stay firm through the long brining and soaking.
- Coarse sea salt
- Draws water out of the peppers and seasons them during the brine stage.
- Vinegar
- Provides the acidity that preserves the peppers and gives the pickle its sharp flavour.
- White cabbage
- Forms the crunchy, savoury filling that fills the peppers.
- White mustard seed
- Adds a sharp, pungent flavour to the stuffing.
The step that matters
Stuff the peppers tightly. Packing the filling firmly leaves little air inside, so the peppers keep their shape and the pickling liquid can penetrate evenly.
Swap the cabbage
How well each one fits the dish's main ingredients (pepper, vinegar, mustard):
- Horseradishfits better
- Radishfits about as well
- Lettucefits about as well
- Cabbagethe original
Fit is the average pairing score against pepper, vinegar, mustard. Candidates are from the same food group and used in at least 100 recipes.
