I followed a simple recipe of 250g of brown sugar and 110ml of water with 25g of butter. With no measuring apparatus at hand I guessed the ratios. As you can see from the picture there is a fair bit of smoke, this was around the point at which the fire alarm went off. I question whether a a Teflon coated pan would have been a wiser choice but perhaps not as I may have caused it irreversible damage.
I finally ended up with five apples coated in burnt sugar. They taste absolutely foul but they sound fine and that is what is important.
