I used this book a lot when I was learning to cook and building a recipe file. I no longer need it as a reference, but recommend it to anyone interested in learning to make his or her own candy. The directions are clear, the ingredients, for the most part, easy to obtain and the results almost always perfect the first time if you follow the directions. It's a worthwhile little book if you have the time and interest in learning old-fashioned candymaking. No microwave directions -- the book was published in 1970.
