As with other culinary endeavors, it would help if you can practice following the measurements in candy recipes exactly. Though a small margin of error every now and then is acceptable, the quality of your candies will depend largely on the harmony of the ingredients - and this can only be achieved if the proportions of the ingredients are balanced. Sugar, the main ingredients of all candies, is also the biggest threat to a good batch of candy or chocolate. Too much or too little sugar can cause problems for your final batch. Be sure to invest in the proper measuring tools before you proceed to cooking some candy at home. We will discuss the various essential tools you will need at a later section in this book. The most important difference between homemade candies and store-bought candies is the quality and safety of the food itself.
