Wash the strawberries thoroughly and remove the stems.

Dice the strawberries and divide them into two bowls: one for mashing and one for topping.

Mix the diced strawberries with sugar, adjusting sweetness to taste.

Mash the strawberries lightly with a fork or spoon, keeping a slightly chunky texture.

Place the mashed strawberries into a transparent glass cup.

Pour milk over the mashed strawberries and add the reserved diced strawberries on top.
