Sort of bushcraft, many years ago when at scout camp, in the days when cooking over a fire was the norm, we used to make an oven with one of the old square biscuit tins covered in mud . We cooked the chicken perfectly but the pudding was tinned treacle sponge, and neglecting to read the instructions we did not pierce the tin before putting it in the oven.Some time later the oven door blew off as the tin exploded, and the rest of the day was spent removing said treacle sponge from the outside of the tent, which if i remember correctly was a canvas vango force 10 mk 4
Ooh, hot treacle!
