Treviso radicchio gives this Veneto preparation its defining bitterness, balanced by mild prosciutto cotto and melting Asiago. The radicchio is cooked before filling so excess moisture does not collect inside the roll.

Taleggio brings creaminess and aromatic depth while Speck contributes smoke and salinity. The filling must stay restrained so the veal remains the principal ingredient and the wine sauce can keep the dish elegant rather than heavy.

This Veneto style version combines mild prosciutto cotto with Asiago, sage and a dry white wine pan sauce. The cheese should melt into a soft center while the sauce remains glossy and clean, without cream.
