Either - we used Roe Fillet, but loin would work equally fine - Mrs C says fillet, coating of haggis, wrapped in puff pastry, crimped at either end, pierce the top - 25 mins at 220 degrees - no pre-cooking of the meatfillet or loin? id of thought fillet would be over cooked
Try haggis in lieu of pate - totally different taste as you would expectMrs Gunn often cooks "Veni-Welli".
She will use one entire backstrap from a roe, or both from a muntjac, using a mix of paté and chopped mushrooms between the venison and the pastry.
Delicious both hot and cold!
