Pigs' trotters with ginger and vinegar

Pigs' trotters with ginger and vinegar, Last year, I posted a recipe for Pig's trotters with vinegar which I got by interrogating my MIL for her secret recipe. I never cooked this traditional Cantonese food myself because MIL made the pig's trotters often. There was usually a pot of it on the back burner. Sadly, MIL passed away last month and in, the process of clearing out her kitchen, I found half a dozen bottles of the special vinegar she used. I decided I would replicate her recipe. Then I unearthed a twenty year old slow cooker, unused, in its original box. I am a fan of the pressure cooker and never cooked with a crock pot. But the pig's trotters have to be simmered for hours and it seemed a good idea to use a slow cooker. I discovered that the slow cooker is the perfect pot for cooking pig's trotters.
