Notes
Whole Black Truffle Alternatives?Whole fine black truffle is expensive and hard to find.You can use a whole summer black truffle or a truffle infused oil or paste as an alternative. Not 'Italian' SausageDon't use fennel-heavy 'Italian Sausage' sold outside of Italy for this recipe. This kind of sausage is almost never used in traditional Italian recipes. Instead choose a simple sausage with wine, garlic, salt and black pepper.
