Firebox stove Chocolate Muffins

I've had this Billy set since the 80's when petrol was 70p per gallon and I had a 2-1/4 (petrol) Lightweight Landrover

Thought I'd try and use it as an oven with the Firebox stove, so bought some stainless steel bowls 39p each and a cooling rack (to cut down) for 99p from Home Bargains

I was wanting to cook with wood out in the hills - But :-

So Plan B a Tantonka Meths stove in the kitchen

30 minutes and it's 300*F and in with the Muffin mix

15 minutes later the stove ran out of Meths, re-fueled and gave it another 15 minutes

tooth pick stick test came out wet so another 15 minutes
Perfect !

Just want it to stop raining to try Wood and see what Bread cooks like.
