I have been unable to find Quark at our local supermarket so decide to look for a recipe on the internet. Voila, it was there on a blog by Peanut Butter Boy. Sounds easy enough and I can't wait to try it. Hopefully I'll be able to use it instead of Ricotta which it ridiculously expensive in NZ as it is imported from Australia. Have now made this recipe and can confirm that it was extremely easy to make and totally delicious. No more store bought cheeses for me.
