01 - Combine sugar and water in a small saucepan. Heat gently, stirring constantly until sugar completely dissolves. Remove from heat and allow to cool to room temperature.
02 - Add mango, strawberries, cooled simple syrup, and lime juice to blender or food processor. Blend on high speed until completely smooth and no fruit chunks remain.
03 - Taste the mixture and adjust sweetness with additional sugar or acidity with more lime juice as needed. Blend briefly to incorporate any additions.
04 - Pour mixture into a shallow, freezer-safe container. Cover tightly and place in freezer for exactly 1 hour to begin setting process.
05 - Remove container from freezer. Stir mixture thoroughly with a fork, breaking up any ice crystals forming around edges. Return to freezer immediately.
06 - Continue removing from freezer every 30 minutes and stirring with fork for 2 to 3 hours total. Sorbet is ready when firm, smooth, and no ice crystals remain.
07 - Let sorbet sit at room temperature for 5 to 10 minutes before scooping to soften slightly for easier portioning.
