It's very simple to freeze strawberries.
You can use frozen strawberries for making smoothies, shakes, sorbets, ice cream, jam, fruit sauce, cakes, and anything else you like.
So here is HOW TO FREEZE STRAWBERRIES:
Wash the strawberries under running water.
Hull them, meaning remove the leafy green bits.
And remove/cut off all bruised bits.
Place the strawberries on a paper towel so they start drying out.
I put a double layer of paper towel on top of my drying mat.
Get another piece of paper towel and gently dry them one by one.
Place them on a single layer in a Ziploc bag. The bag should be big enough so the strawberries don't overlap.
Zip well and remove as much air as possible.
Place the bag in the freezer maintaining the strawberries on a single layer until they are all frozen.
After that you can place the bag any way you want cause frozen strawberries won't stick together.
See? The frozen strawberries didn't get stuck to each other and you can easily get the amount you need without having to defrost the whole batch.
