For a quicker option, after soaking the gammon (step 1) try wrapping the joint in a silver foil parcel and roasting for 20 minutes in an oven set to 170°C/gas mark 3, then finish by glazing in a marinade and crisping up in the oven for 30 minutes at 220°C/ gas mark 7. If choosing this option, make sure the joint has a good amount of fat, as this will help to keep the gammon moist as it cooks.
Dominic Chapman uses a traditional method to bake his gammon. By coating the meat in a bran paste before cooking long and slow, the meat is permeated with a pleasant nuttiness and is kept moist by the protective bran coating.
The most common flavours matched to roast gammon are honey and cloves, complementing the rich, salty quality of the meat. Why not branch out a little when next serving roast gammon - James Mackenzie pairs gammon with scrumpy cider and Emily Watkins serves her gammon lardons with a pea salad, as well as a twist on the traditional egg.
In terms of marinades and glazes, Josh Eggleton recommends using a honey, mustard and clove mix to coat the gammon before it is roasted - mustard and cloves adds piquancy while honey gives the meat a slightly sticky and sweet finish. This is also the case with marmalade or maple syrup - both great ingredients to smear onto gammon prior to roasting.
