Ingredients
Directions
Prepare
Finely chop the green tomatoes, cabbage, cucumbers, and silver onions.
Sprinkle with salt and let sit overnight.
Soak and spice
In the morning, drain the brine and soak the vegetables in a mixture of vinegar and water for 1-2 days.
Drain again.
Mix in the spices: mustard seed, celery seed, turmeric, and cinnamon.
Make the pickle
Boil 2 gallons of vinegar with 4 pounds of sugar and pour over the vegetables.
Pour off the liquid and heat it again for 3 mornings.
On the third morning, mix 1 pound of mustard flour with 1 pint of salad oil and combine with the vegetables.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the sharp acidity that preserves the vegetables and gives the pickle its tang.
- Sugar
- Balances the sharp vinegar with sweetness and helps round out the overall flavour.
- Mustard flour
- Adds concentrated mustard pungency and thickens the dressing slightly when combined with oil.
- Mustard seed
- Contributes a sharp, pungent bite and a textural pop in the finished pickle.
- Cabbage
- Forms the bulk of the chopped vegetables, giving the pickle its crisp body.
The step that matters
Draining after the overnight salting. Salt draws water out of the chopped vegetables into the brine. Draining that liquid thoroughly before the vinegar soak keeps the pickle from being diluted and helps the vegetables absorb the vinegar evenly.
