Remember, if something is worth doing, it is worth doing correctly. That said, the key to making perfect cookies is merely a matter of preparation and precision. To begin with, read your cookie recipe thoroughly before baking. Make sure that you have all of the necessary ingredients before you continue. Next, use good tools and utensils. Sometimes, the craftsperson is only as good as his or her tools. By using good tools you can minimize mistakes and improve the quality of your product. Lastly, you should use top quality ingredients. Unlike in the fairytales, you can't turn lead into gold. If you use poor quality materials, you'll create an inferior product. So, to make perfect cookies you should use the highest quality materials available. Bon apatite!
