01 - Combine sugar and water in a small saucepan. Heat gently while stirring until sugar completely dissolves. Remove from heat and allow to cool to room temperature.
02 - Place diced mangoes, strawberries, cooled simple syrup, and lime juice in a blender or food processor. Blend until completely smooth and uniform in texture.
03 - Taste the blended mixture and adjust sweetness or acidity as needed by adding more sugar or lime juice to achieve desired flavor balance.
04 - Pour the mixture into a shallow, freezer-safe container. Cover tightly and place in freezer for 1 hour to begin setting process.
05 - Remove container from freezer and stir mixture thoroughly with a fork to break up any ice crystals forming at the edges. Return to freezer immediately.
06 - Continue removing from freezer every 30 minutes and stirring with fork for 2–3 hours total, until sorbet reaches firm yet smooth consistency throughout.
07 - Let sorbet stand at room temperature for 5–10 minutes before serving to soften slightly for easier scooping. Serve in chilled bowls.
