Equipment
Method
- Wash the strawberries thoroughly under cool water, hull and halve them.
- In a heavy-bottomed pot, combine the strawberries and lemon juice and heat over medium until the mixture begins to bubble.
- Stir in the pectin and bring the mixture back to a rolling boil. Add all the sugar while stirring constantly.
- Boil for exactly one minute while stirring continuously. Test for doneness using the plate test.
- Add unsalted butter to reduce foam that has formed on top before jarring.
- Ladle the hot jam into sterilized jars, leaving about 1/4 inch headspace, and seal tightly.
- For longer shelf life, process jars in a boiling water bath for about 10 minutes.
