Green Tomato Pickle

Ingredients

Directions

Prepare the vegetables

  1. Layer the tomatoes, onions, and green peppers in an earthen vessel with salt and let stand overnight.

  2. In the morning, drain the mixture for 1 hour.

Cook the pickle

  1. Pour 3 pints of cider vinegar over the vegetables.

  2. Add ½ cup of sugar, cloves, cinnamon, and the bag of allspice.

  3. Cook gently for 30 minutes after boiling begins, keeping the cover partly off.

  4. Just before removing from heat, add mustard seed and stir gently with a wooden spoon.

Rest and finish

  1. Transfer to an earthen jar and let sit in a cool place for 1 month.

  2. After a month, boil the mixture again with ½ cup of sugar, adjusting to taste.

  3. Remove the spice bag before sealing in jars, and add a red pepper pod if desired.

  4. To prevent breaking, place a long spoon in each jar before filling.

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

What each ingredient does

Green tomatoes
Form the bulk of the pickle, softening into tender pieces while holding their shape during cooking.
White onions
Add savoury depth and sweetness that mellows during the long cooking and resting.
Cider vinegar
Provides the acidity that preserves the pickle and gives it its sharp, tangy flavour.
Granulated sugar
Balances the vinegar's sharpness and rounds out the sweet-sour flavour.
Mustard seed
Contributes a pungent, slightly bitter aroma and crunch that lingers in the finished pickle.

The step that matters

Draining after salting. Salt draws water out of the vegetables overnight; draining off that liquid keeps the pickle from becoming watery and lets the vinegar brine be absorbed instead of diluted.

Swap the onion
