I get mine from Morrisons and its always with the cottage cheese.  I love Quark, I eat it straight from the tub!!  I have also found that it makes lovely creamy mash, but it needs plenty of seasoning.
 
I also like it with fruit, I think it tastes like fromage frais.
 
OO yummy, off to spoon some into me gob ;0)
