I suddenly have a yearning for lekvar, otherwise known as prune butter. Specifically I am looking for lekvar filled pierogies, but will be satisfied to find a source of the lekvar somewhere here in San Francisco so I can make them myself if need be. When I lived in NYC many years ago there was a place called "Lekvar by the Barrel" on upper First Avenue. In addition to bulk lekvar, they had a variety of bulk paprikas and other Hungarian goodies. Alas, the owner H. Roth called it quits long before I left NYC and I have never found a place like it anywhere else.
