You need this:
(for 1 liter of liquor)
- 7-8 fresh strawberries, remove crowns
- 2 to 3 drops Greensweet liquid stevia strawberry (optional)
- a liter of water
This is how you make it:
Puree in the blender 500 ml water, stevia and the strawberries to a liquid mass. Pour over in a bottle, and fill with water. Tighten the cap well and shake well. Put in the fridge, cold at its best!
