Preserved Green Tomatoes

The tomatoes and lemons can be sliced and held separately in the refrigerator overnight before combining with sugar and cooking. However, once combined with sugar, the mixture should be cooked promptly to prevent excessive liquid extraction that could dilute the final preserve.

For pantry storage, process filled jars in a boiling water bath for 10 minutes, then cool completely and store in a cool, dark place for up to 1 year. Alternatively, store in the refrigerator without processing for up to 3 months. Once opened, refrigerate and use within 1 month. The preserve will continue to thicken slightly as it ages.
