First, chop the raspberries in a blender. If you don`t like grains in your drink, you should pass the pulp through a sieve. Otherwise just add the coarsely chopped peaches and mix to a puree. Then add the peach juice. Finally add orange juice. The amount can be varied to achieve the desired consistency. I always take so much that I get around 100ml of liquid for 2 servings (including the peach juice). If you like it very sweet, you can sweeten the whole thing with sweetener or sugar, but I think the smoothie is sweet enough.
Tip:
With canned peaches you can take the juice out of the can.
