Wash the fruits. Remove the stalk from the strawberries and quarter them. Divide the nectarines and apricots, then core and dice. Mix the quark, milk and honey. If it`s not runny enough, add a little more milk. If it`s not sweet enough, add a little more honey. Mix the fruit with the sauce and place in serving bowls. If you like, sprinkle the pistachios over it.
