Farmgirl'S Green Tomato Relish - cooking recipe

Ingredients

2 lbs green tomatoes, cored and chopped
1 lb white onions or 1 lb yellow onion, chopped
3/4 lb sweet red pepper, cored and chopped
1/2 lb tart cooking apple, such as 'Granny Smith', cored and chopped
6 garlic cloves, finely chopped
1 cup apple cider vinegar
1 tablespoon kosher salt or 1 tablespoon sea salt
4 jalapeno peppers, cored, seeded if desired, and finely chopped
2 tablespoons cilantro, chopped
1 teaspoon ground cumin (optional)

Preparation

Combine the tomatoes, onions, peppers, apples, garlic, vinegar, and salt in a large,nonreactive saucepan and bring to a boil. Reduce the heat and simmer, stirring occasionally, until thickened, about an hour.
Stir in the jalapenos, cilantro, and cumin and simmer for 5 more minutes. Carefully puree the mixture using a stick blender or in a traditional countertop blender (in batches if necessary) until still somewhat chunky.
If canning, return the pureed relish to a boil, then ladle the hot mixture into hot jars, leaving 1/4-inch head space. Process 15 minutes in a boiling-water canner. Store in a cool, dark place.
