Ingredients
Directions
Salt and drain

Stir in the ground mustard and mix all ingredients well.
Pack and seal
Pour the mixture over the cucumbers and seal while hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Make up the bulk of the pickles and give them their crisp bite when kept well drained.
- White onions
- Add savory sweetness and aroma that mellows during the overnight salting.
- White mustard seed
- Adds sharp, pungent heat and a grainy texture to the brine.
- Ground mustard
- Thickens the brine slightly and adds pungent mustard flavor throughout.
- Granulated sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Horseradish
- Contributes a sharp, pungent aroma and bite to the finished pickles.
The step that matters
Squeezing out the moisture. Excess water left in the vegetables dilutes the pickling liquid and softens the cucumbers. Removing as much as possible keeps the brine strong and the pickles crisp.
