Ingredients
Directions
Prepare the cucumbers
Soak the cucumbers in strong saltwater overnight.
Rinse the cucumbers and place them in a jar.

Boil the spice bag in fresh vinegar for one hour.
Add red pepper pods and horseradish strips among the pickles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, bulk body of the pickle that absorbs the brine and vinegar.
- Vinegar
- Provides the sharp acidity that preserves and flavours the pickles.
- Brown sugar
- Adds sweetness and depth that balances the sharpness of the vinegar.
- Molasses
- Adds dark colour, rich sweetness and a deep, treacly flavour.
- Cloves
- Contribute warm, aromatic spice flavour as they steep in the hot vinegar.
The step that matters
Pouring scalding vinegar over the cucumbers daily. Vinegar that is not hot enough or is applied irregularly will not fully penetrate and acidify the cucumbers, leaving them soft or unpreserved. Repeated hot applications over three days gradually draw out brine and firm the pickles while building acidity.
Swap the cucumber
How well each one fits the dish's main ingredients (vinegar, mustard, allspice, clove, cinnamon, pepper, horseradish):
- Shallotfits better
- Radishfits better
- Beetrootfits about as well
- Cucumberthe original
Fit is the average pairing score against vinegar, mustard, allspice, clove, cinnamon, pepper, horseradish. Candidates are from the same food group and used in at least 100 recipes.
