Ingredients

Directions

Prepare the vegetables

  1. Combine green tomatoes, pickles, onions, cauliflower, red peppers, and green string beans in a large bowl.

  2. Dissolve 2 cups coarse sea salt in 4 quarts of water, pour over the vegetables, and let stand for 24 hours.

  3. Heat the brine with the vegetables, then drain them well.

Make the sauce and finish

  1. In a bowl, mix 1 cup flour, 4 tablespoons mustard, 1 tablespoon turmeric powder, and 1 cup sugar into a smooth paste with a little water.

  2. Add 2 quarts of hot vinegar to the paste and pour it over the vegetables.

  3. Cook until heated through, being careful not to boil them to avoid softness.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Thickens the vinegar sauce so it coats the vegetables.
Mustard
Adds sharp, pungent flavor that balances the sweetness and acidity.
Sugar
Sweetens the pickle and balances the sharpness of the vinegar.
Hot vinegar
Provides acidity that preserves the vegetables and gives the sauce its tang.
Green tomatoes
Provide firm texture and tartness that hold their shape in the pickle.

The step that matters

Cook until heated through, without boiling. Boiling softens the vegetables and can break down their texture, so they should be heated only until warm and still firm.
