Prep the fruit. If using fresh fruit, peel and dice the mango, and slice the peaches. Frozen fruit can go straight into the blender.
Add the base ingredients. In a blender, add mango, peach, banana, yogurt, and 3/4 cup of your chosen liquid.
Flavor and balance. Add vanilla, a small pinch of salt, and sweetener if your fruit isn’t very ripe.
Blend until smooth. Start on low, then increase to high for 30–45 seconds.
If it’s too thick, add a splash more liquid. If it’s thin, add a few ice cubes or more frozen fruit.
Taste and adjust. Check sweetness and texture. Add a touch more honey, a few ice cubes, or extra liquid to get it just right.
Serve cold. Pour into chilled glasses.
For a little flair, top with a peach slice or a sprinkle of chia seeds.
