Quark is brilliant stuff. You can marry it off with so many things. In the past I have chopped beetroot, onion, sweet and sour gherkin etc and had that with 2 ryvitas, or even with chopped fresh fruit. It is great to make soups creamy, to use on toast, on top of strawberries, the list is endless.
We get it here without a problem and at times this place is really third world !!!! I am sure that in Bromley you will have no trouble.
I agree with Claireybell, please put the recipe here,
Good luck and enjoy.
