Strawberry Jam in 45 Minutes

Instructions:

1. Combine the halved strawberries, lemon juice, and salt in a medium heavy-bottomed saucepan. Use a potato masher to lightly crush the berries, leaving some chunks for texture.
2. Place the pan over medium-low heat and add the sugar. Stir frequently until the sugar completely dissolves into the strawberry juices and the liquid is clear and shimmering.
3. Increase the heat to medium-high and bring the mixture to a full rolling boil. Stir constantly to prevent the sugars from sticking to the bottom until the mixture becomes a glossy, thick glaze.
4. Perform the Plate Test by dropping a small dollop of jam onto a chilled plate from the freezer. After 30 seconds, push the jam with a finger; if it wrinkles and holds its shape, the jam is finished.
5. Transfer the hot jam into a sterilized half-pint glass jar and seal with a lid.
