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 before proceeding.
02 - Place diced mangoes, halved strawberries, cooled simple syrup, and fresh lime juice into a blender or food processor. Blend on high speed until completely smooth and uniform in texture, approximately 1-2 minutes.
03 - Taste the blended mixture and adjust sweetness or acidity as desired. Add additional sugar or lime juice in small increments, blending briefly after each addition to incorporate evenly.
04 - Pour the smooth mixture into a shallow, freezer-safe container, leaving ½ inch of space at the top for expansion. Cover tightly with lid or plastic wrap and place in freezer for 1 hour.
05 - Remove container from freezer. Using a fork, vigorously stir the mixture to break up any ice crystals that have formed along the edges and bottom. Return to freezer immediately.
06 - Continue removing from freezer every 30 minutes and stirring vigorously with fork to break up ice crystals. Repeat this process 4-5 times over 2-3 hours until sorbet reaches firm yet scoopable consistency.
07 - Let sorbet sit at room temperature for 5-10 minutes before serving to soften slightly. Scoop into chilled bowls or serving dishes. Garnish with fresh mint leaves or additional lime wedges if desired.
