During season, when strawberries are seen flooding the market and are available at reasonable rates, I buy large stocks and freeze a few batches to work with them later on. This way I can enjoy them year long, even when they are not in season.
frozen strawberries in a zip-lock bag
To freeze fresh Strawberries: Wash the strawberries and drain them. Remove the leaves and spread them out on a kitchen towel for 30-45 minutes so that they air dry. Then, spread them on a rimmed baking sheet and freeze them for 2-3 hours. Once frozen, transfer the strawberries to a zip-lock bag and remove as much air as possible from the bags and seal them air tight. Freeze the frozen strawberries in the bags until needed.
Classic Strawberry Jam
Strawberries – 850 gms (around 1.8 pounds), fresh/frozen
Granulated sugar – 2 cups
Lemon juice – 2 tbsp
Butter – 1 tbsp
Cut off the top stalk part of the frozen/fresh strawberries. In a large glass mixing bowl, add the frozen strawberries, sugar and lemon juice. Mix well and let sit at room temperature for 1 hour. Later, transfer it all to a food processor and pulse just until the strawberries are just chopped. DO NOT MAKE A PUREE. Transfer this to a saucepan, and bring to a boil and high heat, once boiling let cook at medium heat for 30-45 minutes or until a jam consistency is reached. Add butter to reduce the foam. Keep stirring and keep a close eye on it. During the last 15 mins, lower the heat to medium low. Remove from heat once done. Spoon the prepared jam into a sterilized Mason canning jar ( I recommend using 1 cup jars instead of one large jar for the jam) and seal the jar according to instructions. Once it is at room temperature, refrigerate the jar to store.
Note: This is a preservelike spread and not a true preserve and must be refrigerated to avoid spoilage, because it contains a higher proportion of fruit to sugar and retain more fresh fruit flavor.
