They're the Marlon Brando of grapes: intense, explosive and (hey, if we're talking about the later years) round.

Concord grapes — their dark blue-purple skins give them a brooding quality, their stubborn seeds might amount to difficult behavior. But what makes them a premiere talent of American grapes is their rich, distinct, full-bodied flavor.

No other grape compares.

Yet, for far too long, they've had "I-coulda-been-a-contender" status at markets. The grape that loaned its trademark jammy flavor to so much soda, juice and jelly has had an uneven career as a table grape. Maybe because their "slip skin" makes them fragile; the skin is thick but isn't attached to the flesh as with European varieties, so the grapes don't hold up as well during shipping and storage. And then there are those seeds.

But fresh Concord grapes are so delicious. Bite into it and the fruit explodes away from the skin.

To cook with them is to discover a new level of their lusciousness. Alice Waters has an easy grape preparation that works well with Concord grapes — roasting them whole on the vine. Cut them into small, attractive bunches, drizzle them with olive oil and treat them to a 450-degree oven for 10 minutes. The warm, juicy grapes burst through their skins during cooking. Waters doesn't call for any other seasoning, but if you sprinkle them with Maldon sea salt, the crunchy-tender flakes are the perfect complement to the soft, sweet fruit. They're great with sweet or savory dishes, on ice cream or alongside grilled meat.

In fact, Concord grapes are generally fantastic with meat. Made into a wine reduction to sauce seared pork tenderloin medallions, they are reminiscent of fresh cherries. They get meltingly soft cooked in wine, their sweetness mitigated by garlic and shallots. The sauce takes on a deep-purple glazey shine.

At Campanile restaurant, chef-owner Mark Peel makes a deep-flavored granita with Concord grapes, beaujolais wine, whole cloves and black pepper. It's gorgeous, with big grape flavor and the kick of pepper and clove.

Peel says you can substitute a Sonoma pinot noir for the beaujolais. Neither should be more than 13 percent alcohol. Too high an alcohol content can keep the granita from freezing, he cautions.

And Concord grapes are surprisingly suited to a traditional schiacciata Italian flatbread. It's a focaccia-type bread that's stretched and shaped by hand before small indentations are made all over the top of the bread with the fingers. Lightly sugared Concord grapes are sprinkled over the top of the bread before baking.

It's easy to seed the grapes by pressing the tip of a knife into the stem end of the grape and flicking out the seeds. But it's not necessary; you can leave the seeds in.

Warm from the oven, the grapes are scented with fennel, rosemary and orange peel. The jammy, luxurious grapes settle into the soft, fragrant bread.

Seeds are a small price to pay.
