One of the things I miss most about Yonkers, NY, where I grew up, was the German potato salad found at Lorenzen's Deli on Yonkers Ave.
It was the most perfect one I ever ate. I grew up on it like I did with NY pizza. It had no mayo - maybe vinegar with the slightest hint of sugar and lots of parsley and it had a real tang to it which I guess was the vinegar.
Do you know what I am talking about Michael?
