It was half price in tesco, finest wiltshire cured gammon joint, and the instructions say to roast it. MIL says i can treat it like a ham and soak it to remove saltiness, boil and then roast and glaze it like i would a ham. Will this work or will i ruin it ? I don't want it too salty and i really wanted ham; if i treat it like a ham will it behave like one?
