Don't crowd your pan when frying foods. And don't turn the food until it is cooked thoroughly on one side.
Fry meat, chicken, sea food, and vegetables on high heat so they don't lose their juices and flavor.
Blind bake tart bases to have an even raised crust and make it less soggy when adding fillings.
Store roasted vegetables while still hot in plastic bags for a few minutes so they are easier to peel.
