Boiling a Gammon Joint is quicker than roasting alone and gives moister Gammon slices.

How to boil gammon?
When boiling gammon you need to cover with water, you can add herbs, peppercorns, onion or vegetables can also be added to boiling step if desired.
We love the taste of the ham as it is & prefer to add flavour from the glaze instead! So we keep it simple with just a couple of bay leaves.
Make sure to submerge the gammon joint to cover over the top with water, if you lose water during cooking add more.
Also it should be noted that although its called boiled ham or gammon, it should not be boiled for the whole duration, simply bring to the boil then lower to a simmer.

The roasting time for boiled gammon is 30 minutes, this cooking time is the same for all boiled gammon joint sizes. The gammon is cooked already you are just roasting the fat layer and adding a delicious glaze.
Pressure cooker gammon method
To speed things up, you can use a instant pot, pressure cooker to cook the Gammon Joint. No checking in on it just leave for it for the allotted time.
If you haven't got a Pressure Cooker, I highly recommend the Pressure King Pro, we have had ours for 3 years now and use it every week!
You will see below in recipe card both instructions for how to pressure cook gammon using a pressure king pro or instant pot, or how to pan boil the gammon!
Removing skin from Gammon?
After the gammon has boiled, it is best to remove the thick skin, leaving the fat layer still intact.
The gammon fat will be super soft and ready for scouring in a diamond pattern, we then added cloves for extra flavour!
In all honesty, we went a bit OTT with cloves here, but wanted it to look even and well covered for the photo! You can use half the amount we used!
Honey and mustard glaze
A simple glaze for roast gammon is this honey and mustard glaze, it is easy to make with equal amounts of runny clear honey and English mustard.
You could try out our Sticky Beer and Honey Glaze instead for another option.
Pour your chosen glaze over the top of the gammon joint, making sure to save some for to add again halfway through roasting.
I also highly recommend adding a layer of foil under the gammon joint as the honey is hard to clean off the baking tray!
How long to cook glazed gammon in oven?
Oven roast glazed gammon in a preheated oven at 180°c fan / 200°c / 400°f for 30 minutes, halfway through add more glaze to the top.
When finished remove from oven and cover loosely with foil, allow to rest for 10 minutes before carving.
You have got to agree that it is quite a masterpiece roast dinner to bring to the Christmas dinner table!
There is enough to serve 8 people with a 2kg gammon joint.

Frequently Asked Questions?
Most store bought gammon joints in the UK are ok to use straight away, I normally soak for a few hours to remove some of the saltiness. If buying from the butchers ask if it will need soaking first, it depends how they have cured it?
Yes, keep netting on when boiling to keep it together, and remove before removing skin to roast.
The tough gammon skin should be removed, leaving behind a layer of fat which soaks up the glaze and becomes crispy when oven baked.
