Stop in at Karl's on Rte. 1 North in Saugus and look in awe at the immaculate deli case full of German specialties. Karl's is a butcher shop and charcuterie only, so you're going to do the cooking. The place is as clean as an operating room, and the sausages are magnificent. My favorites are the coarse bratwurst, and they have excellent headcheese and Black Forest ham. And lo and behold, they even make their own frankfurters! Trust me your sausage consumption will go up when you find this place.
