Pasta with Sausage and Cream

A dish I learned from my good friend Andrea, who is originally from Rome but has collected unusual pasta dishes from all over Italy. This is clearly a peasant dish, but the presence of sausage, butter, and cream makes it special enough for guests. Use well-seasoned “Italian” sausage; it can be hot if you like. That made without casing—in patties or bulk—will save you a step.
