With our wonderful summer days upon us, it’s time to embrace some of the more delightful summer produce. Squash are gourds – fleshy vegetables protected by a rind. Even though most people identify squash with vegetables, from a botanical standpoint, they’re actually fruits because they contain the seeds of the plant. They are divided into two main groups: summer squash and winter squash. Summer squash have soft shells and tender, light-colored flesh and are picked while immature. Winter squash have hard shells, and darker, tougher flesh and seeds and are not harvested until they are mature.
The most popular summer squash is the familiar green zucchini. It is only one of several common types of summer squash, which vary in shape and color. All are similar enough in flavor and texture to be interchangeable in recipes. It’s hard to keep up with all of the names and varieties, but summer squash generally fall under four broad groups: Cousa, Pattypan/Scallop, Yellow, or Zucchini.
Summer squash is an enjoyable vegetable that contains a list of health benefits and is rich in nutrition. Generally, there is little variation in nutritional value between varieties.

Summer squash has a very good source of potassium, which helps to control blood pressure. In addition, it is high in manganese, a mineral that helps the body process fats, carbohydrates, and glucose. Aside from the lack of fat in summer squash, the magnesium quantity has been shown to reduce the risk of heart attack and stroke.

Picking Your Squash
Choose squash that are firm and heavy for their size. The stem end should be fresh and green. Look for squash with unblemished, glossy skin, and avoid those showing nicks, pits, bruises or soft spots. Summer squash taste best when small to medium size, not more than eight inches long. Overly large squash may be fibrous, while tiny ones may have inferior flavor. A hard rind indicates an overly mature squash that will have hard seeds and stringy flesh.
Store unwashed summer squash in a protected place inside the refrigerator, wrapped in a damp towel or plastic bag for up to one week. Avoid storing squash near apples, avocados, or peaches that are all natural ripening agents that release ethylene gas. The gas will discolor and decay zucchini and other dark green squash.
Summer squash also freezes very well. It will not retain its texture, but frozen squash works great in wintertime stews and soups and breads.
Squash have no parts that go to waste. The entire vegetable – rind, seeds, and in some cases, the blossom – can be eaten. To begin cooking, wash well under running water and trim the ends. Summer squash need not be peeled or seeded unless it is oversized and has a thick skin or large seeds.
