When the people of Dublin, Ireland elected their first Jewish mayor, Robert Briscoe in 1956, baseball legend Yogi Berra allegedly exclaimed "Only in America!" This St. Patrick's Day recipe for corned beef and potato pancakes with pickled cabbage creme fraiche was created in that same spirit. Potato latkes, traditionally served at Hanukkah, are the inspiration for these crispy potato and onion patties. But in this version, flavorful shreds of corned beef along with a pickled cabbage topping are added as a tribute to Ireland. Be sure to use pre-shredded hash brown potatoes, which can be found in either the produce or dairy section of most grocers. These are much drier than freshly grated potatoes and will ensure crispy results that hold together well in the frying pan. If you can't find those, you can peel and shred your own russets. But before cooking them, roll the shreds up in a clean dishtowel, then squeeze out as much moisture as possible.
