01 - Combine sugar and water in a small saucepan. Heat gently while stirring constantly until sugar completely dissolves. Remove from heat and allow syrup to cool to room temperature before proceeding.
02 - Add diced mangoes, strawberries, cooled simple syrup, and fresh lime juice to blender or food processor. Blend on high speed until completely smooth, approximately 1-2 minutes, scraping down sides as needed.
03 - Taste the blended mixture. Add additional sugar if more sweetness is desired, or extra lime juice for increased brightness. Blend briefly to incorporate any adjustments.
04 - Pour the smooth fruit mixture into a shallow, freezer-safe container. Cover tightly with lid or plastic wrap. Place in freezer for exactly 1 hour to begin setting process.
05 - Remove container from freezer. Using a fork, vigorously stir and mash the mixture throughout to break up any ice crystals forming at edges. Return to freezer immediately.
06 - Continue removing sorbet from freezer every 30 minutes and stirring vigorously with fork to break ice crystals. Repeat this process for 2-3 hours until sorbet reaches firm, smooth consistency throughout.
07 - Let sorbet stand at room temperature for 5-10 minutes before scooping. This slight softening makes scooping easier and improves texture. Serve in chilled bowls or as an elegant dessert garnish.
