Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
To Pickle Barberries and Siberian Crabs
Ingredients
Directions
Prepare the fruit
Cut half the length of the stalks from the crabs.
Remove leaves and discolored barberries.
Brine and store
Place the fruit in stone jars and cover with boiled and cooled brine made from salt and alum.
Check occasionally for scum or mold and remove any scum or mold.
Replace the brine with freshly made brine as needed.
Make and add the vinegar
Add alum to enough vinegar to cover the fruit and boil with white peppercorns.
Strain the peppercorns.
Let the vinegar cool before pouring it over the fruit.
Pour the cooled vinegar over the fruit.
Ensure the crabs are not ripe to prevent bursting in the pickle.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barberries
- Provide the tart fruit that is preserved and pickled in the brine and vinegar.
- Siberian crabs
- Provide the fruit that is pickled; they must be unripe so they hold together in the pickle.
- Coarse sea salt
- Draws water out of the fruit and helps preserve it in the brine.
- Vinegar
- Adds acidity that preserves the fruit and gives the pickle its sharp flavour.
- Alum
- Helps keep the fruit firm so it does not soften or burst in the pickle.
The step that matters
Use unripe crabs. Ripe fruit is soft and breaks down or bursts in the acidic liquid. Unripe fruit has firmer flesh that holds its shape through pickling.
