  • 1 medium gammon joint, approx 1.3kg
  • 1½ litre bottle ginger beer
  • 1 tbsp English mustard
  • 3 tbsp ginger preserve


  1. Put the onion and 10 cloves in the base of the slow cooker then nestle in the gammon joint. Pour over the ginger beer then cover and cook on LOW for 7 hours until the gammon is tender, but still holding its shape. You can cool then chill the gammon at this stage if you prefer.

  2. Heat the oven to 200C/180C fan/ gas 6. Carefully remove the skin from the gammon leaving a layer of fat behind. Score the fat in a diamond pattern with a sharp knife, making sure you don't cut into the meat, then stud the centre of each diamond with cloves.

  3. Mix the mustard and ginger preserve in a bowl, spoon or brush over the gammon then bake for 20 mins until golden and sticky. If roasting from cold you will need to add another 20 mins to the cooking time.

Given that there isn’t a four and a half option I’d rate this a five! I had to use some poetic license as it’s lockdown and I couldn’t get all of the ingredients locally. My gammon was 1 kilo but in the end I cooked it for the same time in the slow cooker and 10 min more in the oven which was perfect. I couldn’t get gloves so substituted star anise after researching on the web for alternatives. My ginger preserve had to be ginger marmalade and despite the fact that it was warned not to use a sugar free fiery ginger beer that was all I had so in the end as o was as unsure what the ginger beer actually did to the meat to be on the safe side I diluted a couple of teaspoons of sugar in a little hot water and added that to the ginger beer. Normally I would pre boil gammon to rid some salt prior to cooking but this time I followed the recipe and didn’t bother as it was cooking in sweet liquid anyway. It turned out great! I was worried that the fizzy pop would make the gammon sweet but it just seems to tenderise it and intensify the actual gammon flavours. The only thing we weren’t enamoured with was the glaze which was very sweet but in all honesty we aren’t fans of sweet sticky glazed and it was true to the recipe but the actual meat was the best gammon I’ve ever cooked so will onehunfred percent repeat the method. I did already cut down the amount of preserve to 2 tbsp but for our family’s preference would probably cut to equal amounts with the mustard next time or even use a little honey and mustard instead. All round a winner though!!! And don’t be afraid of using diet ginger beer, unless you plan on using the cooking liquor for a sauce, probably doesn’t need the additional sugar I think it’s more of the acidic effect that helps.

Used less ginger beer as the quantity stated wouldn't fit in my slow cooker, missed out the onion and added a spoonful of honey to the glaze. Left in the oven for longer...till it went nice and browned all over - delicious!

Very easy to do, I normally cook the gammon and cut it in half then glaze the other half. Yummy

Very easy recipe, simple to follow. I didn't have ginger preserve so substituted with grated fresh ginger and apricot preserve. Would probably make it again because of how easy it was

We cooked this yesterday as a test run for our Christmas ham and I can't begin to describe how good it is. The ham is very tender and the ginger flavour is beautiful. When it was cooking it smelt like Christmas in my kitchen. Would definitely recommend this as one to try.

How long would you cook a bigger joint for example 5 kg for?

So very quick to make (less than 5 minutes to prep) and really delicious result. I glaze with a mixture of honey/mustard prior to oven baking. A staple in the house and always tastes great.

I can also only get diet ginger beer, if I added sugar would that work? I’m unsure why the diet version isn’t recommended

Hi, The diet version, as you have guessed has no sugar in it so you won't get the sticky effect. With regard to your other question, you can leave the cloves out. Lulu

Is there anything I can substitute for the cloves please? I can’t get any locally during lockdown

Instead of the ginger and mustard glaze could I just coat it with runny honey and then bake?

Thanks for your question - you can glaze with honey instead or a mix of honey and mustard works well.

How long would you cook the ham for in a slow cooker at medium / high? Hoping for a 12.30pm lunch and I don't want to be up at 5am to start cooking, haha!

Thanks for your question. We haven't tested this recipe on High so cannot give specific advice but 3 - 4 hours should be sufficient.

Thanks for your question. We would not recommend using diet in this recipe as the flavour will not work well.

I used diet ginger as I couldn’t get anything else and it turned out great
