I can tell you a funny Quark story.

As a boy I had a nanny from Naples, Italy. Her name was Luisa. Luisa's father was a baker in Napoli. And Luisa loved my mother's Suabian Cheesecake, made with Quark. My mom showed her how to make it and when she returned to Naples, she wanted to show her dad how to make the famous cheesecake. Unfortunately, the Quark didn't take kindly to the voyage en train from the north of Germany to Napoli and turned sour. This is why to this day you still cannot buy Suabian cheesecake in Naples.

Quark, fromage blanc and mascarpone are all hard to find or hard to pay for in the US.
