The pasta cases can be made, cooled and removed from the pans one day before the party. Store in an airtight container at room temperature. The bolognese sauce can be made two days ahead; keep it covered in the fridge. Assemble the baskets up to 3 hours before the party. Note
Calves liver should be cut into paper-thin slices then quickly seared because too much cooking will destroy its soft, delicate texture. Your butcher will slice the liver thinly for you. Note
