Remove the green leaves from the strawberries. Wash the strawberries once and then puree them with a hand blender. Squeeze the limes and add the juice to the strawberry puree. Next, squeeze the oranges and add the juice to the strawberry mixture as well. Let the strawberry and orange juice rest in the refrigerator for about 1 hour so that it cools down nicely.
Stir once before serving.
Serve the aperitif in tall glasses.
Tips: For decorative purposes, cut into a strawberry and attach it to the glass. Put a straw in if you like.
