Ingredients
Directions
Prepare the tomatoes
Slice the tomatoes and sprinkle with salt.
Let sit overnight.
In the morning, pour clear water over the tomatoes and drain immediately, ensuring all water is removed.
Pack and cover
Pack the tomatoes in jars in layers with mustard seed, horse-radish, and green pepper, using about 6 green peppers for each peck of tomatoes.
Cover the packed jars with cold vinegar and tie cloth over the tops.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Firm, smooth, green tomatoes
- Provide the main body of the pickle, staying firm when they are not cooked.
- Coarse sea salt
- Draws water out of the tomatoes, firming them for crisp pickles.
- White mustard seed
- Adds a sharp, pungent flavor that layers through the packed jars.
- Horse-radish, finely chopped
- Adds a pungent, sharp heat that flavors the pickle.
- Cold vinegar
- Acidifies the tomatoes, preserving them and giving the pickle its tang.
The step that matters
Draining the salted tomatoes thoroughly. Any water left behind dilutes the vinegar and weakens preservation, and it can soften the tomatoes. Draining immediately and removing all water keeps the pickle firm and better protected.
