In a bowl, mix strawberries and sugar; refrigerate for 1–2 hours to create syrup.
Chill syrup, then spoon 3–4 tbsp into a glass.
Pour cold milk over syrup and stir gently.
Serve with ice cubes or whipped cream if desired.
Notes
Adjust sugar ratio (1:1 for sweet, 1:0.5 for balanced, 1:0.2 for low-sugar). Use fresh strawberries for best flavor. Enjoy immediately after mixing for best taste.
