Ingredients – 1 pound green slicing tomatoes (or 1 1/2 pounds green cherry tomatoes)
For the Brine – 1 cup white distilled vinegar (5% acidity) – 1 cup water – 1 tablespoon kosher salt
Basic Pickling Spice Mix – 1 teaspoon yellow mustard seeds – 1 teaspoon celery seeds – 1 teaspoon coriander seeds – 1/2 teaspoon black peppercorns – 1/2 teaspoon whole allspice
Cut larger (slicing) tomatoes into 1/2-inch wedges, and cut smaller (cherry or grape) tomatoes in half.
In a small saucepan, bring all of the brine ingredients to a boil and stir until the salt is dissolved. Remove the brine from heat.
Fill a hot, clean quart jar with the pickling spice mix of your choice. Pack the jar tightly with the tomatoes.
