Clean, wash and cut the rhubarb and strawberries into pieces. Put them in a pot together with 2 tablespoons of honey, bring to the boil and cook for about 5 minutes while stirring. Let it cool down. Mix buttermilk, quark, lime zest and 1 tablespoon honey. Put the buttermilk-curd mixture and the rhubarb-strawberry compote alternately into 6 glasses (each containing approx. 250 ml) to create a "swirled effect".
