Ingredients
Directions
Prepare the vegetables
Peel the onions and wash the other vegetables.
Cut the large vegetables into pieces.
Cover the vegetables with brine strong enough to float an egg for 24 hours.
Drain and cover with equal parts of vinegar and water for 12 hours.
Make the pickling syrup and pour
On two mornings, pour the following boiling hot mixture over the vegetables: white mustard, vinegar, turmeric, brown sugar, and celery seed.
On the third morning, add ground mustard mixed with flour and cold vinegar to the boiling mixture and boil for 10 to 15 minutes.
Stir in olive oil, cool, and pour over the pickles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the bulk of the pickle, becoming crisp-tender after brining and soaking.
- Onions
- Add savory flavor and body to the pickle mix.
- Brown sugar
- Adds sweetness that balances the sharp vinegar.
- Vinegar
- Provides the acidity that preserves the vegetables and gives the pickle its tang.
- Ground mustard
- Adds sharp, pungent flavor and helps thicken the pickling liquid with flour.
- Flour
- Thickens the mustard mixture so it coats the vegetables.
The step that matters
Adding the ground mustard and flour mixture. Flour mixed with mustard must be blended into cold vinegar first, then added to the boiling liquid, or it will clump. Boiling it briefly lets the starch thicken the sauce and cooks off raw flour taste.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, mustard, vinegar, turmeric, sugar, celery, flour):
