Although some chayote varieties differ in appearance, those found in American grocery stores are pear-shaped and pale green in color. The fleshy fruit's outer skin contains a few ridges but is mostly smooth. Chayotes grow to about 6 inches long with an average weight of 3/4 lb. The large, tender seed within is edible. The taste of chayote squash is similar to summer squash and cucumbers.
In spring, after the last frost, plant the whole chayote fruit with the stem end almost exposed above ground. Full sun, warmth and a long growing season are needed along with plenty of water. Provide either a trellis or nearby tree for support; chayotes grow and dangle from slight stems on perennial climbing vines that can reach a height of 40 feet or more.
The soft texture of chayote squash allows for easy preparation for use in sauces, juices and children's food. This versatile fruit can be steamed, creamed, stuffed and baked, breaded and fried, added to soups, stews or casseroles and eaten raw in a salad. Crisp, young chayotes make a suitable substitute for water chestnuts in Asian dishes. Mexicans dry the fruit before processing into jam. In India, chayotes are cultivated for human consumption and for livestock feed.
Chayote squash is a good source of vitamin A, vitamin C, calcium, potassium and fiber. It is low in fat, calories and sodium and contains no cholesterol. The seeds are especially rich in amino acids. Chayotes are sold throughout the year in large supermarkets as well as Asian, Spanish and Indian specialty food stores. Choose fruit that is firm; tender skin indicates poor quality.
