Then slash the surface of the joint in criss cross pattern to about 3-5mm depth.
In a small bowl mix up 3 tablespoons of honey, 1 tablespoon of english mustard, some salt and pepper and a squeeze of 1/2 an orange. Mix well. Taste it and adjust mustard and seasoning to taste.
Spread some of the glaze all over the joint. Loosely cover with foil and Roast in the oven at 160 degrees for about an hour, basting with the glaze every 15 minutes or so.
