Glazed gammon makes an excellent centre piece for a family Easter brunch, it is popular with the young and old. You can vary the size of the gammon you cook according to the number of guests you are serving. Allow 20 minutes boiling/ baking per 450g/1lb plus an extra 20 minutes (half boiling and then half baking) . Adjust the amount of the glaze according to the size of the gammon. Here I have prepared a small gammon for 4-6 people just double the size of the gammon and glaze ingredients for 10-12 people.
