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
Pickling Spice Mix
1/4 cup packed brown sugar
1 teaspoon curry powder
1/4 teaspoon cumin seeds
1/4 teaspoon whole allspice
3/4 inch fresh ginger, sliced into thin coins
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. Pour the hot brine over the tomatoes, covering them completely and leaving 1/2 inch headspace. Stick a chopstick or “bubbling” tool into the jar and move it around to release any trapped air bubbles.
Wipe the rim clean, seal with a lid and band, and process in a boiling water bath for 15 minutes (adjusting the time for altitude as needed), or store in the fridge!
