Summer Squash Basics

When European explorers came to the America’s, squash was one of the 3 major foods the native Indians used, along with beans and corn. Europeans had never seen them before, so they thought they were melons. Squash seeds have been found in Archeological digs in Mexico that date back to between 9000 and 4000 B.C.  Columbus brought squash seeds back to Europe following his explorations in the Americas.

There are many varieties of summer squash, including zucchini, crookneck, sunburst, yellow and patty pan squash. Summer squash is picked in the summer before it has ripened, whereas a winter squash is picked when it is fully ripe. Summer squash is eaten cooked, grilled or raw. Even the skin is edible in summer squash.

Zucchini comes from the Italian Zucca that means squash. Though squashes didn’t originate in Italy, it is believed that the Italian name was adopted because the Italians are credited with developing this food. The zucchini as we know it wasn’t used in this form until the late 1800’s in Italy, probably near Milan, because many of the early varieties are named after nearby Italian cities.

Zucchini is simply an elongated, cylindrical, usually green variety of summer squash. There are three varieties of zucchini: Elite, Senator and Spineless Beauty. The Senator and Spineless Beauty are both hybrids and take less time to harvest, on average a week less than the Elite Zucchini.

Yellow squash belongs to the summer squash family along with the zucchini and scallop squash. Its pale yellow fruit is prized in a variety of dishes from stir-fries to roast vegetable recipes. It produces heavily throughout the summer months, with each plant turning out several squashes a week at the peak of production. Harvesting the yellow squash at its pinnacle of ripeness ensures it is tender yet flavorful, as overly ripe squash is tough and unappetizing.

Crookneck squash are typically yellow with bent or “crooked” necks. They are not as popular as zucchini and straightneck squash because they are not as easy to package and ship. Breakage can occur at the neck during harvest and transportation. Examples of crookneck squash include Destiny II, Dixie, Gentry, Medallion, Meigs, Prelude II and Supersett.

Straightneck squash are among the most popular varieties of squash because of the ease in harvesting and transportation, compared with crookneck squash. Examples of straightneck squash include Cougar, Enterprise, Fortune, Golddrop, Lemon Drop L, Liberator III, Lioness, Multipik, Monet, Seneca Prolific and Superpik. Straightneck squash can typically be harvested between 40 and 50 days after the first fruit appears. Most have a large bulb that tapers down toward a thin neck. The typical color of straightneck squash is yellow, but some are a light green.

When selecting patty pan squash at the market, look for squash that are regularly shaped, without bruises or nicks. Steer clear of any with discolored areas or moldy spots. If you’d like to steam or roast the patty pans whole, choose smaller squash, as they’ll cook more quickly and thoroughly. However you decide to prepare them, a pound of squash should serve nicely as a side dish for two or three people.

White Bush Scallop squash  is pale green in color. This tender squash, also referred to as Patty Pan squash, makes a delicious basis for stuffed squash. Similar to other summer squashes, White Bush Scallop squash is low in calories and contains potassium and vitamin A.  Mature squash is generally more nutrient-rich than when it’s immature. Because of its mild taste, a variety of fillings work well with scallop squash.

What to Look For: Look for summer squash that are firm and heavy for their size; the skin should be brightly colored and blemish-free. Because they are harvested earlier, smaller squash are more tender than larger ones and have thinner skins; choose squash that are less than eight inches long.

How to Store: Refrigerate in a plastic bag for up to four days; do not wash until ready to use.

Zucchini Salad with Shaved Parmesan

Add minced fresh jalapeño, if you want more spice.

Makes 6 servings

Ingredients

  • 1 medium lemon
  • 2 tablespoons extra-virgin olive oil
  • 1/2 teaspoon freshly ground pepper
  • 1/4 teaspoon salt
  • 2 pounds small zucchini, cut into lengthwise slices about 1/2 inch thick
  • 1/2 cup sliced almonds, toasted
  • 1/3 cup thinly shaved Parmigiano-Reggiano cheese

Directions:

  1. Bring a small saucepan of water to a boil over medium-high heat. Remove the peel from lemon with a vegetable peeler, making sure not to include any white pith. (Reserve the lemon.) Cut the peel into thin slivers. Add to the boiling water and cook until soft, 4 to 5 minutes. Drain and set aside to cool.
  2. Squeeze the juice from the lemon into a small bowl. Add oil, pepper and salt and whisk to combine. Set aside.
  3. Preheat grill to medium-high or place a grill pan over medium-high heat until hot.
  4. Oil the grill rack or a grill pan. Grill zucchini slices, turning once, until tender, 6 to 8 minutes.

Make Ahead: Prepare through Step 4, cover and refrigerate the zucchini, lemon peel and dressing for up to 1 day. Bring to room temperature before serving.

Tips: Use a vegetable peeler to shave thin curls or slivers off a block of hard cheese like Parmigiano-Reggiano. To oil a grill rack, oil a folded paper towel, hold it with tongs and rub it over the rack. (Do not use cooking spray on a hot grill.)

Whole Wheat Pastry

Makes enough for 2 pies. Remember to roll this out thinly so that it doesn’t become too bready.

Ingredients:

  • 2 teaspoons active dry yeast
  • 1/2 cup lukewarm water
  • 1/4 teaspoon sugar
  • 1 large egg, at room temperature, beaten
  • 1/4 cup olive oil
  • 1 cup whole wheat flour
  • 1 cup unbleached flour 
  • 3/4 teaspoon salt
Directions:
Dissolve the yeast in the water, add the sugar, and allow to sit until the mixture is creamy, about five minutes in large bowl of mixer. Beat in the egg and the olive oil using the paddle attachment. Combine the flours and salt, and stir into the yeast mixture.
Switch to the dough hook and knead the dough until it comes away from the sides of the bowl. Knead for a few more times, just until the dough is smooth-do not overwork it.
Place in a lightly oiled bowl, cover the dough tightly with plastic wrap, and allow to rise in a draft-free spot until doubled in size, about one hour.
Turn the dough out onto a lightly floured surface, gently knead a couple of times, and cut into two equal pieces. Shape each piece into a ball without kneading it. Cover the dough loosely with plastic wrap, and let rest for five minutes. Then roll out into thin rounds, as directed in the recipe above.
If not using the second piece of dough right away, freeze the dough for another time.
