Salt and drain
Layer the green tomatoes and chopped onions in a bowl, sprinkling salt between the layers.
Let them sit overnight.
Drain the mixture through a colander.

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 and provide its firm, tart body.
- Onions
- Add savory flavor and aroma that blends into the pickling liquid.
- Coarse sea salt
- Draws water out of the tomatoes and onions, firming them and seasoning the pickle.
- Vinegar
- Provides the acidity that preserves the pickle and gives it its sharp tang.
- Red peppers
- Add sweetness, color and mild crunch to the finished pickle.
The step that matters
Stirring while the mixture boils. Sugars and solids in the mixture can scorch on the bottom of the pot during the 15-minute boil. Frequent stirring spreads heat evenly and prevents burning, which would give a bitter taste.
