Make the most of end-of-season tomatoes with this sweet and tangy Green Tomato Jam recipe. Easy to prepare, spiced with ginger and cinnamon, and perfect for canning or freezing.
Wash and core the green tomatoes. Chop them into small pieces—no need to peel.
Place the tomatoes, sugar, lemon zest, lemon juice, ground ginger, cinnamon, and salt in a large, heavy-bottomed pot. Stir well to coat the tomatoes with the sugar.
Set the pot over medium heat. Bring the mixture to a gentle boil, then reduce to a low simmer. Stir occasionally at first, then more frequently as the jam thickens to prevent sticking.
Continue cooking for 45–60 minutes, until the mixture becomes glossy and thick. The tomatoes will break down into a soft, spreadable texture.
For a smoother jam, use an immersion blender to puree to your desired consistency.
Spoon hot jam into sterilized jars, leaving ¼ inch of headspace. Wipe the rims clean, seal with lids, and process in a boiling water bath for 10 minutes, or refrigerate for immediate use.

Jam thickens as it cools—don’t overcook.
Fresh ginger can be used instead of ground (1 tablespoon grated = 1 teaspoon ground).
