Viviana Varese honours the traditional Milanese dish osso buco in her veal recipe. Keeping the bone as the focal point, Viviana swaps the classic veal shin for bone marrow, which is topped with delicate tartare of veal onglet and fillet. Finished with rich mustard mayonnaise and delicate vinegar snow, one taste of this dish and you'll be fighting 'Mario' for the bone . . .
