Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Stuffed Peppers
Ingredients
Directions
Prepare the peppers
Remove the tops and seeds from the peppers.
Soak the peppers in a strong brine overnight.
Make the filling
Chop the cabbage, mix with salt, and let it sit for 15 minutes.
Boil the vinegar with the sugar in a pot.
Press out the moisture from the cabbage and add it to the boiling vinegar.
Add celery and mustard seed to taste, and heat through.
Pack and seal
Stuff the mixture into the peppers and pack them into glass jars.
Boil the vinegar hard and pour it over the stuffed peppers, then seal the jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peppers
- Their flesh softens during brining and holds the filling while adding sweet, mild flavour.
- Cabbage
- Provides crisp texture in the filling, which is kept crunchy by pressing out excess moisture first.
- Vinegar
- Provides the acidity that pickles the peppers and preserves the filling.
- White sugar
- Balances the sharp acidity of the vinegar with sweetness.
The step that matters
Pressing the moisture out of the cabbage. Cabbage holds a lot of water. If it is not pressed dry before going into the hot vinegar, it dilutes the pickling liquid and makes the filling soggy instead of crisp.
Swap the celery
How well each one fits the dish's main ingredients (pepper, egg, vinegar, sugar, cabbage, mustard):
- Tarragonfits better
- Dillfits better
- Capersfits about as well
- Celerythe original
Fit is the average pairing score against pepper, egg, vinegar, sugar, cabbage, mustard. Candidates are from the same food group and used in at least 100 recipes.
