Green Tomato Chow Makes about 3 cups
- 2 lb. small green tomatoes, cored and thinly sliced
- 1 medium yellow onion, thinly sliced
- ¼ cup fine sea salt
- 1 tbsp. whole black peppercorns
- 2 tsp. cardamom seeds
- 2 tsp. coriander seeds
- 1 tsp. whole allspice berries
- 1 tsp. yellow mustard seeds
- 5 whole cloves
- 2 bay leaves
- 2 dried chiles de árbol, stemmed
- 1 stick cinnamon, broken in half
- 1 2″-piece ginger, peeled and thinly sliced
- Cheesecloth, for spices
- 3 cups white wine vinegar
- 2 cups sugar
2. Next day, pour tomato mixture into a colander and rinse well under cold running water. Spread tomatoes and onions in a single layer onto a double thickness of paper towels; blot dry with more paper towels.
3. Heat peppercorns, cardamom, coriander, allspice, mustard, cloves, bay leaves, chiles, and cinnamon in a 4-qt. saucepan over medium-high heat. Cook, stirring occasionally, until seeds begin to pop, 3–5 minutes. Transfer spices along with ginger to a piece of cheesecloth; tie into a tight package.
4. Add vinegar and sugar to saucepan and bring to a boil over medium-high heat; cook, stirring, until sugar is dissolved, 1–2 minutes. Add spice package and reserved tomato mixture; reduce heat to medium-low. Cook, stirring occasionally, until tomatoes have broken down and sauce is very thick, about 1 ½ hours. Let chow cool to room temperature before serving. Store in refrigerator up to 2 weeks.
