You know the feeling, legs feel like they're not yours and no matter how much you will them to keep spinning they just don't want to play ... you've run out of energy and you need to do something pretty quickly or sitting on the edge of the trail sobbing may be the result. Flapjack is your saviour, I'm not going to get all scientific and start talking GI and carbo loading, so you'll just have to trust me when I say, flapjack will get you home. Even folk who can't boil water without burning it can make flapjack if they follow the WRT 'almost fool proof' recipe ... where vagueness and near enough rule.
1/ Get yourself a pan.
2/ Put 6oz of marg' + 6oz of brown sugar (normal granulated will do) + 6 tablespoons of syrup in your pan.
3/ Locate the oven and turn the hob on, stick the pan on the hot bit until everything in the pan has melted.
4/ Find some oats (the porridge you bought, promised to eat but never did, will do) pour the oats in to your pan and keep stirring. Add more oats until you've got something that's around the consistency of thick porridge.
5/ Go mad and fling something else in there (not compulsory), dried fruit, nuts, choc chips, belly button fluff ... whatever you fancy.
6/ Now you'll need something to cook it in. A baking tray 1/2" deep and 10" x 8" would be great but whatever you find will more than likely be fine.
7/ IMPORTANT grease your baking tray with marg'. Give the inside a right good rub.
8/ Spoon/tip/fling your mixture in to your tray, level it out a bit and stick it in the oven. 200 degrees for 20 minutes should do the trick.
9/ Get it out and while it's still warm cut it up.
That's it, job done, the trail food of the gods ... told you it was simple.
