Cut stems off strawberries and add to a saucepan

Crush strawberries with a potato masher to release their juice

Add sugar and lime (or lemon) juice and turn the heat to medium high

When the jam starts to boil, turn to medium heat and let lightly boil for about 10 minutes, stirring occasionally, or until a candy thermometer reaches 220°F  – an alternate way to know if your preserves are done is to put a plate in the freezer and let it get cold while your strawberries are boiling. After 10 minutes, place a quarter size dollop of preserves on the cold plate and if you can run your finger through it without it filling in, your preserves are set. If it’s too runny on the cold plate, then keep trying every few minutes.

When your preserves are done, let them cool slightly and pour them into their refrigerator container.

Refrigerate until you’re ready to use.
