How to Make It
In a bowl, whisk the sugar with the pectin. In a food processor, pulse half of the strawberries until finely chopped, then transfer them to the sugar mixture. Repeat with the remaining strawberries. Add the lemon juice, ginger and salt and stir until the sugar is dissolved, 5 minutes.
Spoon the jam into clean glass jars or plastic containers, leaving 3/4 inch of space at the top. Let the jam stand at room temperature until slightly thickened, 30 minutes. Refrigerate until the jam is chilled and set, 1 hour.
