Add water to a small sauce pan and bring to a low simmer and add the sugar and extract. Stir until dissolved and bring to a boil for about a minute. Remove and allow to cool.
Meanwhile, prep all fruit -rinsing, peeling, cutting- as necessary and add to a large mixing bowl.
Once cooled, add syrup in a small bowl and whisk with yogurt. Once combined, add to fruit and toss.
Serve room temperature, or cover and refrigerate for 30 minutes before serving.
Top with fresh mint immediately before serving.
