01 - Combine diced strawberries, sugar, and lemon juice in a small saucepan. Cook over medium heat for 5-7 minutes, stirring occasionally, until strawberries soften and release their juices to form a syrupy consistency. Lightly mash with a fork to break down larger pieces, then remove from heat and allow to cool completely.
02 - Distribute the cooled strawberry sauce evenly between two tall glasses, ensuring each glass receives an equal portion of the sauce at the bottom.
03 - Place a few slices of fresh strawberries into each glass atop the sauce layer to provide additional texture and visual appeal.
04 - Slowly pour cold milk over the strawberry sauce and fresh strawberries in each glass. Add ice cubes if desired for extra chill.
05 - Gently stir the drink once or twice to create a marbled swirled effect between the red sauce and white milk. Serve immediately while cold.
