Ten top chefs in Coupeville will engage in a heated competition this weekend to see who cooks the best mussel chowder.

And it should be really good mussel chowder. The competition is one of the highlights of the annual Penn Cove Mussel Festival, which is in its 22nd year of celebrating Whidbey Island’s popular mollusk.

Andreas Wurzrainer, chef and owner of Christopher’s on Whidbey, is the two-time defending champion. He won the contest last year with a mussel chowder made with smoked paprika and corn. The year before that, he won won with a New England-style chowder made with apples.

“It’s always fun to see their reaction,” Wurzrainer said of the chowder enthusiasts enjoying his contest entries.

He didn’t give any indication as to what’s in store for this year’s contest, maintaining that he hasn’t come up with this year’s chowder ingredients yet. Wurzrainer will decide his latest entry, which will come as a sort of a mussel epiphany, in the days leading up to the weekend-long mussel festival.

There’s sure to be a wide variety of chowders vying to become the festival’s best. In addition to Christopher’s, Toby’s Tavern, the Tyee, Miriam’s Espresso, the Pizza Factory, The Cove, Anna’s Tea Room, the Oystercatcher, Kim’s Cafe and the Mad Crab are all creating chowder for the competition.

The Penn Cove Mussel Festival provides a weekend’s worth of fun for the whole family.

“I guess we’re trying to make a big deal out of it this year,” said Cindy Olson, owner of Aqua on Front Street, who is helping organize the festival.

Approximately 5,000 people attended last year’s Penn Cove Mussel Festival.
