Green Tomato Preserves
Ingredients
Directions
Soak small tomatoes in weak salt water overnight.
The next morning, make a syrup by boiling sugar and skimming it.
Add the tomatoes to the syrup and cook until they can be easily pricked with a fork.
Remove the tomatoes and place them in jars.
Add a few slices of lemon to the syrup and boil until it thickens nicely.
Pour the syrup over the tomatoes and seal the jars.
