Every time I buy liverwurst, I have good childhood memories of my mother buying it at the Joseph Horne department store. Like so many old-fashioned dept stores, it featured more than just clothing: a bakery, a deli, etc. On Saturdays, we'd go downtown (Pittsburgh) for piano lessons, and then over to Horne's for liverwurst or ham.
Curiously, though, she rarely, if ever, fixed liver and onions. Somehow I've developed a deep appreciation for the dish.
