Directions
Prepare the chopped vegetables
Chop fine equal quantities of green tomatoes, cucumbers, onions, and green peppers.
Sprinkle with salt.
Let them stand for one day.
Pour off the water.

Sprinkle salt over the tomatoes.
Let them stand for twenty-four hours.
Drain off the juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provides the bulk of the chopped pickle and its tart, firm texture.
- Vinegar
- Provides the sharp acidity that preserves and flavours the pickle.
- Sugar
- Balances the sharpness of the vinegar with sweetness in the tomato pickle.
- Salt
- Draws water out of the vegetables, firming them and concentrating flavour.
- Cinnamon
- Adds warm aroma to the sweet pickle syrup.
- Cloves
- Adds warm, pungent aroma to the sweet pickle syrup.
The step that matters
Draining and re-pouring the hot pickle. Salting and draining remove water so the pickle stays crisp and does not dilute. Scalding the syrup each time keeps it hot enough to penetrate and help preserve the tomatoes.
Swap the onion
