01 - Combine diced strawberries, sugar, and lemon juice in a small saucepan. Cook over medium heat, stirring frequently for 5-7 minutes until strawberries soften and release their juices, forming a syrupy consistency. Lightly mash strawberries with a fork to achieve desired texture. Remove from heat and allow to cool completely.
02 - Distribute the cooled strawberry sauce evenly between two tall glasses, ensuring each receives an equal portion.
03 - Place a few slices of fresh strawberries into each glass for added texture and visual presentation.
04 - Slowly pour cold milk over the strawberry sauce in each glass. Add ice cubes if desired for enhanced chill.
05 - Gently stir the drink to create a swirling marble effect, combining the strawberry sauce and milk. Serve immediately while cold.
