Lightly toast some bread. Add a really, really thin spread of marmalade (optional, but try it…). Top with grated cheese and apply the MAPP torch. You’d be surprised just how close you have to hold it to get the cheese to brown—I started waving it vaguely in the direction of the bread, but ended up playing the flame directly over it.
Really. Blowtorch’s are all very well but marmalade and cheese? Originally found here
