It’s important that you keep your Christmas ham from drying out in the fridge. The best way to do this is to fold the rind back over any exposed surface and store it in a Ham Bag or wrapped in a tea towel. Before wrapping soak the Ham Bag in a mix of 1 litre of water to 2 tablespoons of white vinegar. Squeeze out any excess liquid to leave the bag damp. Repeat the process every couple of days.
