Wash and hull 250 grams of fresh strawberries, then cut them into halves.
In a blender, add the halved strawberries, 500 ml of chilled milk, 4 tablespoons of sugar, and 1 teaspoon of vanilla essence.
Blend the mixture until smooth and creamy. If you prefer a thicker consistency, add a scoop of vanilla ice cream and blend again.
Pour the strawberry shake into tall glasses and garnish with a few sliced strawberries or a dollop of whipped cream, if desired.
