This popular summer squash is shaped like a slightly curved cylinder, a bit smaller at the top than the bottom. A zucchini's skin color can vary from dark to light green, sometimes with yellow markings that give it a mottled or striped look. The off-white flesh has a very pale green cast and the flavor is light and delicate. Common market length is 4 to 8 inches long and 2 to 3 inches thick.
Fresh zucchini is available year-round in most supermarkets, with a peak period during late spring.
Select small zucchini, which will be younger and therefore more tender and have thinner skins. The skins should be free of blemishes and have a vibrant color.
