Hull the strawberries to remove the green tops and slice them into small pieces.
In a blender, add the sliced strawberries, sugar, and vanilla extract.
Pour in 1 cup of milk and blend until smooth.
Taste the mixture and adjust the sweetness if necessary.
Strain the mixture through a fine sieve if a smoother texture is desired.
Pour the strawberry mixture into a glass, filling it halfway.
Add the remaining milk to the glass and stir gently to combine.
