Summer Squash Gratin
The most common summer squashes are green zucchini, the light green flying-saucer-shaped patty pan, and the gooseneck-shaped yellow crookneck. More obscure varieties with different flavors and textures can be found at farmers’ markets. One of my favorites is Costata Romanesco, a ribbed, mottled-green, zucchini-shaped squash. It has a sweet flavor and a texture that doesn’t break down while cooking. Choose small, firm squash with bright skin. Larger ones tend to be watery and seedy. Wash the squashes or rub them clean with a damp cloth. Trim off and discard both the blossom and stem ends. Once cut, squash can be stored in the refrigerator under a damp towel for several hours. The blossoms of summer squash are good to eat as well. Trim off their stems and shake them well to rid them of any bugs they may be harboring. Chop the blossoms, sauté them, and add to an omelet, a pasta sauce, or a risotto. Or cook them whole, stuffed with cheese perhaps, and poached, baked, or dipped in a simple batter and fried.
