Cooking rice
One important thing to remember when making rice is to stir it as little as possible. Once or twice to break it up a little is fine, but excess stirring will make it mushy and stick together.
Potato patties
If you have leftover mashed potatoes lying around, make them into croquettes! Just form the potatoes into patties, heat up a frying pan with a little oil (see 101 for an oil tip), crisp them up on both sides, and you've got a tasty treat!
Sweet Sauces
If you plan on using sauces, marinades or other flavorings in your recipes that contain significant amounts of natural or refined sugars (such as fruit preserves, chutneys, certain kinds of teriyaki and BBQ sauces ect...), just be aware that those flavorings can caramelize and burn very easily when exposed to direct heat. Just be conscious that the outside of whatever you're cooking doesn't get too crispy for your liking.
