Does anyone have any experience of using a hay box*? I'm tempted to make one as I have plenty of polystyrene to use for insulation, and plenty of ply for the box. I'd be interested to hear any first hand experiences.
*Basically a well insulated box that you put a hot casserole dish into and leave overnight to cook from the residual heat, saving fuel as you're not constantly heating the dish in oven/on the hob.
