1 leg or half leg of pork, on or off the bone
For the brine
2.2kg fine sea salt
5 litres water
2 litres good apple juice
2 litres cider
2kg soft brown sugar
A handful of black peppercorns
A handful of coriander seeds 1 tbsp cloves
2 bay leaves
A bunch of thyme
Pared zest of 2 oranges
Equipment
Large stockpot
Large plastic food-grade box
Put all the brine ingredients into a large stockpot, including the spices, herbs and orange zest. Bring to a simmer over a medium heat, stirring regularly to stop the salt and sugar catching on the bottom of the pan. Simmer for a minute or two, then remove from the heat and allow to cool. Pour the brine into a big, deep plastic food box, large enough to fit your pork leg in. Chill the brine until ready to use it.
You need to leave your pork in the brine for 3 days for every kilo it weighs. So if your leg of pork weighs 8kg, you’ll leave it in the brine for 24 days. If you leave it in an extra day or two, it’s not the end of the world. It might be a tiny bit saltier but you can rectify that by soaking the ham for a few hours before you cook it. When you’re ready, immerse the pork in the brine, weighing it down so it is completely submerged. Leave somewhere nice and cool – it may not fit in your fridge.
After the allotted time, remove the ham and wash it under a cold running tap. Pat the ham dry with a clean tea towel and either hang it up in a cool, dry airy place or place on a tray in the fridge. I let my hams dry for 2–3 weeks before I cook them; they mature nicely over this time. However, a home-cured gammon like this can be cooked as soon as it comes out of the brine.
