I've tried everything and nothing bought compares with things you can make yourself. My current favorite is American style pancakes, loads of butter and syrup in the mix plus an extra pinch of salt. 2 eggs will make 10 pancakes! nutella is good as are potatoes (new with skin left on). I will always grab jelly babies if they are available at checkpoints though. I once had some weird homemade salty flapjack balls, sweet and salty goodness. They even had caffeine in them! I haven't a clue how to make them or even where you would buy caffeine but they did the trick. I'm off to Google salty flapjack balls, I may get fired.
