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.
When preparing condiments, make them a little salty so they can be preserved longer.
It's better to avoid the use of aluminium cookware and foils specially when cooking with acidic foods like lemons and tomato paste.
