Need Proscuitto or Parma ham for a starter tomorrow evening (last minute arrangement). Won't be able to get to a deli, will have to be a supermarket. Any recommendations for what I can get that is any good from a supermarket? Or any to avoid? I can most easily get to Tesco, Sainsburys, Aldi, Lidl, M&S. Asda & Waitrose a bit of a trek. Thank you
