The 4th annual Sausagefest is this weekend, and promises to be even meatier and juicier than ever before. And involve red velvet cake. My favorite sausages are the spicy red-hot thuringers at Schmeisser's Home Made Sausage (7649 N Milwaukee Ave, Niles, IL 60714).
Thuringers! These sausages originated in Thuringia, and are lower in fat than most other German sausages. Wikipedia suggests that you prepare them, "roasted over charcoal or on a grill rubbed with bacon." I agree.
