There are a few meals I can say I'm making that will make my children excited (or pretend to be), and this is one of them. Alongside there must be Pie Insides (which is what my daughter has always called leeks in white sauce) and for ultimate gratification, roast potatoes although I usually use goose fat for roast potatoes, I feel the pork belly allows, indeed encourages, the substitution of lard. I'm not convinced that with all that fabulous crackling you do need roasties as well, but I like to provide what makes people happy.
I have advised an overnight marinade, but if I'm making this (as I tend to) for Sunday supper, I often prepare it in the morning and leave it in the fridge loosely covered with baking parchment, or midday-ish and leave it uncovered in a cold place (but not the fridge) for a few hours.
