6. Don't overcrowd your pans
Crowding a frying pan causes the temperature to drop quickly, which won't give you a good sear on meats. And overcrowding a sheet pan or baking dish can lead to soggy vegetables instead of roasted beauties. Cook in two pans or in batches if you have more food than the pan can handle!
7. Experiment but, follow the recipe...the first time you make it.
The next time, you can amend it and make it more to your tastes. This allows for new tastes to be explored before you add your personal touch.
