Beans and their Preparation
Of all the vegetables commonly used for food, BEANS afford the greatest variety. However, there are two principal classes into which all varieties of this vegetable can be placed, namely, string beans and shell beans. String beans include both the pods and the seeds, and are used when the beans are very young. Shell beans consist of the seeds, which are allowed to mature either partly or entirely and are taken from the shells before cooking. Those which are partly developed are cooked when they are fresh, but the ones that are allowed to mature completely are dried and then stored for use at any time during the year. In some cases, the same variety of beans may be used in the three ways mentioned, while in others certain kinds are raised expressly for one of these purposes.
The food value of beans increases as they mature, as will be observed upon reference to Table I. The very young beans, that is, the string beans, which include the pods and all, are comparatively low in food value, being only a little higher than asparagus. To increase the food value of these, fat meat, butter, or other fat is supplied in their cooking, or milk or a cream sauce is added before they are served. Fresh shell beans have much more nutriment than string beans, whereas dried beans are very high in food value. It is this characteristic of dried shell beans that makes them a very good meat substitute.
