Wash the strawberries in water really well and cut the leaves if any. You can use a strawberry huller to make the job more easy.Cut the strawberries in to halves or more to make the blending more easy.
Add the strawberries, sugar, lemon juice and water to the blender.
Blend until smooth!
Filter the juice in fine mesh strainer to remove any seeds residue (optional) and serve in tall glass cups with added ice cubes, enjoy!
Notes
If you are saving the strawberry juice for later use, you should refrigerate it as the juice taste best when used cold. You may also freeze the strawberry juice for a few days or more ( I haven't done this for more than a few days) in ice cube trays and use later.
