Explore the Pacific Northwest as Moveable Feast with Relish travels to Seattle to get a memorable taste for the region known as Cascadia.  Host Curtis Stone jumps aboard a seaplane with Chef Tom Douglas as they head to Coupeville on Wideby island. Chef Tom is the winner of three James Beard Awards, and together with chef Renee Erickon, they are a driving force behind the food scene in Seattle. First stop: a visit to Penn Cove to see where mussels grow in what’s considered the best environment in the region. Next we meet-up with Georgie Smith of Willowood Farms, which is one of the most painted and photographed farms in the Pacific Northwest. With their ingredients in hand, the chefs then collaborate on the creation of a true regional feast that includes steamed mussels; a spiced mussel and saffron soup; and a grilled whole salmon with Walla Walla onions and fava leaves.
