Various methods of cooking ...
bring out nature's finest flavors
Grilling vegetables causes the natural sugars to concentrate and become very
flavorful.
Why does the subject of vegetables inflame such passionate feelings? A brief,
innocent mention of brussels sprouts in a casual conversation can lead to
long-winded diatribes about their vile smell and foul flavor.
Then there's the contentious matter of a cooked vegetable's texture. To some,
asparagus that has been cooked al dente is sublime. But to others, those same
spears aren't tender-crisp at all but downright raw and inedible.
The field of vegetables is so vast, and their cooking methods so gloriously
varied, that there's something for everyone.
So here's a guide to the best cooking methods for seasonal produce.
Moist-heat Methods
Blanching: Vegetables are briefly put into a saucepan of boiling water
and the timing begins immediately. This method doesn't fully cook the food but
softens the texture.
To stop the cooking and set the color, refresh the vegetables by immediately
draining and plunging them into ice water.
Vegetables can be blanched a day in advance of serving. Once they're refreshed,
pat them with paper towels, then wrap them in dry towels, place in a plastic bag
and refrigerate. Finish cooking by sautéing or stir-frying the vegetables.
Blanching and refreshing also are necessary before freezing vegetables to
keep the enzymes from breaking down both color and texture.
Boiling: Here's a myth buster. Adding a pinch of baking soda to boiling
water may indeed help keep vegetables green, but the soda's alkali destroys cell
walls, causing a mushy texture – so skip that idea.
There is, however, a real solution to holding the vibrant color.
“Essentially, with most green vegetables, you can count on having seven minutes
of heat before there is a major color change,” says Shirley Corriher, author of
“CookWise: The Secrets of Cooking Revealed” (William Morrow). “Cooking longer
will cause the natural acids present in vegetables to turn them yellow-brown.”
Vegetables should be added to rapidly boiling water, and the timing should
begin only when the water returns to the boil. Leave the pan uncovered.
Braising: Vegetables contain natural moisture, which releases in cooking.
Lightly brown the vegetables in a little fat, than add a tablespoon or two of liquid
to start the cooking process. Cover the pan and cook slowly over medium-low heat.
Once the vegetable has released its moisture, add only enough liquid to keep it moist.
Steaming: A large pot and a simple steamer basket are the tools needed to cook
vegetables with this method. Don't pack the basket too tightly or the cooking will be
uneven. Bring the water to a boil before placing the covered basket above the pot.
Dry-heat methods
These methods evaporate moisture in the vegetables quickly, which causes the
juices to brown and the natural sugars to concentrate and become very flavorful.
Broiling: The heat source is above the food, making this a great technique for
blistering the skins of sweet peppers or chilies for easy peeling and a smoky flavor. Sliced
vegetables such as eggplant should be brushed lightly with oil to keep them from drying out
under the high heat.
Grilling: This technique is similar to broiling, but the heat comes from below,
and a basting liquid is needed to keep food moist. Grill baskets or a perforated
stainless-steel grid are perfect for keeping small vegetables such as mushrooms from falling
into the fire below. For indoor cooking, heavy grill pans caramelize the vegetables and
give them a wonderful smoky flavor.
Roasting: This has become a favorite technique for cooking vegetables. Toss with
a little olive oil and sprinkle lightly with salt, then roast in a single layer in a shallow,
rimmed baking sheet. The high temperature of 400 degrees or above causes the vegetables
to shrink and lose their natural moisture, which concentrates the sugars and deepens the flavor.
(Baking uses a temperature of 375 degrees or lower.)
Sautéing: The pan size should be large enough to cook the vegetables in a single layer
without crowding. The bottom of the pan should have a light coating of oil, or a mixture of oil
and butter. A nonstick cooking spray also can be used. Set the pan over medium heat and wait for
the oil to become hot before adding the vegetables. Blanch tougher vegetables such as green beans
first to speed the cooking process.
Stir-frying: Basically, this technique is similar to a sauté, but vegetables are cut into
smaller pieces. Use medium-high to high heat for quick cooking and toss often.

Grilled Vegetables With Balsamic Vinegar
6 to 8 servings
- 1 pound medium-thick asparagus
- 3 red bell peppers, cut in half, stemmed and seeded
- 2 yellow summer squash, cut diagonally into 1/2-to 3/4-inch slices
- 2 zucchini, cut diagonally into 1/2-inch slices
- 12 cremini mushrooms
- 12 green onions
- About 4 tablespoons olive oil (divided use)
- 2 tablespoons balsamic vinegar
- 3/4 teaspoon kosher salt (divided use)
- 1/2 teaspoon fresh ground black pepper
- 1 teaspoon chopped fresh basil
- 1 teaspoon finely chopped fresh rosemary
Snap off ends of asparagus and wash well. Wrap in paper towels and set aside.
Cut each bell pepper half into quarters and set aside. Prepare the yellow
squash and zucchini; set aside. Wipe the mushrooms with a damp paper towel, trim
stem ends and cut each in half. Trim and discard ends from the green onions.
Rinse well and pat dry.
Whisk together 2 tablespoons olive oil with balsamic vinegar, 1/2 teaspoon
salt and a little pepper; set aside. Brush vegetables with remaining olive oil
and sprinkle with remaining salt and pepper.
Prepare a charcoal or gas grill for medium-high heat, or preheat a ridged
grill pan for 5 minutes on medium-high. Working in batches, grill the vegetables
until tender and lightly charred all over, about 8 to 10 minutes for bell
peppers, yellow squash and zucchini; 5 to 10 minutes for asparagus; 5 to 7
minutes for mushrooms; and 4 to 5 minutes for green onions.
Arrange the vegetables on a platter, sprinkle with herbs and drizzle with
dressing. Serve the vegetables warm or at room temperature.
