Has anyone tried this? There are some quite expensive but beautiful and efficient looking ‘Wonderbags’ for sale which are basically padded bags for you to put part-cooks food inside casserole dishes- the idea being that they carry on cooking for hours using their stored heat.
I’d love to hear if you bought one, or any similar product, as to whether is was worth it.
They are meant to be good for camping as well as a way of saving fuel.
I am trying an experiment today. I got a polystyrene foam box from the fishmonger (he gave it to me for free) and have packed into it an Irish stew - stewing lamb, onions, potatoes, carrots, celery, stock. I browned the meat and veg in a lidded cast iron casserole and added the stock, simmered for 15 minutes, then I padded it into the polystyrene box with newspapers and old fleece throws. I piled a couple of heavy items on top. I will come back this evening and tell you if it was edible.
