Green Tomato Jam

This green tomato jam is moderately sweet, with the lemon juice and zest enhancing the natural acidity of the green tomatoes. The sugar helps to sweeten the jam just enough without being overpowering, and helps to thicken the jam with the pectin from the tomatoes.

  • 2 pounds green tomatoes, cored and chopped

  • 1 ½ cups granulated sugar

  • 1 teaspoon grated lemon zest

  • 2 tablespoons lemon juice, divided

  • ¼ teaspoon salt


  1. Toss green tomatoes, sugar and 1 tablespoon lemon juice together in a large nonreactive bowl until well combined. Cover and refrigerate for at least 1 hour or up to 12 hours.

  2. Transfer the tomato mixture to a large nonreactive pot and bring to a gentle boil over medium-high heat. Reduce heat to low and simmer, stirring occasionally, until the mixture bubbles, thickens and becomes syrup-like, 35 to 45 minutes. Stir in lemon zest, salt and the remaining 1 tablespoon lemon juice.

  3. Working in batches, if needed, pour the tomato mixture into a blender. Secure the lid on the blender and remove the center piece to allow steam to escape. Place a clean towel over the opening. Process until mostly smooth, 10 to 15 seconds. (Use caution when pureeing hot liquids.) Transfer to a medium nonreactive bowl or a pint-size mason jar. Refrigerate, uncovered, to chill completely before serving, about 30 minutes. Serve chilled or cover airtight and refrigerate for up to 3 weeks.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
