Depending on the mixer and device, chop the fruit and alternate with yoghurt - the amount can be varied freely - and pour vanilla sauce into the container. Mix vigorously once and add a freely selected pure juice gradually until it is ready to drink.
Half a vanilla pod in yoghurt is also recommended instead of the vanilla sauce, but you should add a little more liquid.
Frozen fruit also works great if the machine is designed for it and requires less juice.
Be careful with frozen fruits and small containers. If the yogurt is placed on the frozen fruit, it freezes and becomes hard. It can mean that the fruit can only reach the knife with difficulty.
