Pick and choose fresh strawberries without marks, spots etc. Rinse them in a colander under running tap water. Drain water completely and pat dry the strawberries with a kitchen towel.
Using a paring knife, remove hulls (green leaves). Note - Use paring knife or strawberry huller.
Dab excess moisture, if any, using a clean, dry tea towel or kitchen cloth.
Line a baking tray with parchment paper and place the strawberries.
Place the tray in the freezer, undisturbed for 4 hours or until such time the strawberries are hard as rock.
Remove the tray from the freezer and transfer the frozen strawberries to a zip-lock freezer safe bag or container.
Before sealing the bags, remove excess air to avoid freezer burn.
Store the bag in the freezer, until ready to use.
