It's only occasionally that pork belly strips will go on sale at just over £2 for 500gm in a supermarket like Sainsbury's but even when not selling at such an attractive price, pork belly is a bargain protein.
It's also - when treated right - healthy, and if you're suffering from low Vitamin D, one of the few foods that helps increase it.
67goingon50 has posted pork belly slices before; this newer version is very easy though it requires some planning. The strips are poached in water to tenderise the flesh and release some fat. Then is it is bathed in a punchy sauce, roasted in an air fryer or oven and served with extra sauce. Voila: hand-held pork pops!
If you'd rather not have any fat at all, or if very tender pork is required (for oldies, say, or toddlers) double the poaching time until the pork is ultra-tender. Remove fat, pop a skewer into the meat and proceed as described...but reduce cooking time by a third.
