Adding a bit of honey to baked good will help them stay moist, it has a chemical that draws in water.

Regularly sharpen your knives either on a steel or arkansas stone. My parents had a knife that was very dull, basically just pushed its way through things, I spent a few hours sharpening it and now it is their sharpest knife.

I'm not much of a cook, but I've discovered this little tidbit...

Don't store bananas and bread in the same area. The bread will absorb the banana flavor and ruin it.

Here's a great camping tip...I always take a bunch of those disposable foil cake pans or roasting pans with me. That way you can make as big a mess and you want cooking your scrambled eggs (or creamed corn or whatever) and there's no messy pot to clean up afterwards - just throw it away. (Normally I'm very conscious about throwing stuff out but this is an exception.....I hate to scrub out pots and pans when I'm camping!!!)

If you are using dried herbs, you also get a lot more flavor if you rub them in your hands first before putting them in the pot -- there's some technical reason for it it's like the heat from your hands releases some of the spices oils... particularly good for dried basil and oregano.
