I normally get the one wrapped in plastic in brine, don't know about the one from the butcher, sorry!! You normally cook corned beef for an hour per kilo. I add a couple of carrots cut in half, large onion cut in half, bay leaf, about six cloves, 6 peppercorns, powdered mustard, brown sugar, vinegar and nutmeg. Place meat in and cover with water. Bring to simmering point and when simmering cook as I said, 1 hour per kilo. YUMM!!

I make my own sauce with butter, flour and milk then add nutmet, seeded and hot english mustard and grated cheese. My DH LOVES it, (so do I as a matter of fact LOL!!)

I am sure your IL's will love it. ENJOY!!
