Growing up in Germany, I used to love having Mettwurst on a sandwich for lunch. Mettwurst is an uncooked pork sausage, cured and smoked I think, that is spreadable. It is similar in nature to tartare if I remember correctly.
It being uncooked pork, I am not sure if it is at all available in the U.S. Does anyone know if you can purchase it somewhere, and if so, where?
I don't know if they'll have it, but try Karl Ehmer's in Ridgewood, Queens. It's on Fresh Pond Rd., a few blocks from Metropolitan Avenue.
ehmer's makes a nice mettwurst, as does schaller and weber: a good number of delis carry the latter (i get it at a place in jackson hts called Gourmet Fantasy Foods, but have seen it in several other Queens meat markets).
If you are in Manhattan, you may want to check at the German butcher in the Grand Central Sta foodhall.
The best (echt) german sausages and meats in the NY metro area can be found at Union Pork Store in Union NJ. They have everything--Mettwurst, Bratwurst, Leberkaes, Bauernwurst, Suelze, Landjaeger, you name it. It's located just west of the town center on the main drag (Morris Ave?) across the street from the big Shop Rite store.
If you can get there you won't be disappointed.
