Out on Eastern Long Island, real food and real estate rule, somebody who knows recently told me. This wisdom was proven at a special dinner at the Pollock-Krasner House on the waterfront Springs site where the artist couple lived, and at Guild Hall’s annual Garden as Art tour featuring vegetable gardens at several spectacular estates. On a late August Thursday chef Michael Rozzi from East Hampton’s 1770 House, riffed on the recipes found in Robyn Lea’s Dinner with Jackson Pollock (Assouline).Taking the steps for the abstract expressionist’s clam pie, he put the filling in a clam shell, like a baked clam, and served it along with Pollock’s home baked white bread spread with salmon to a dozen guests seated around the table Lee Krasner acquired to host Jackson’s dealers and collectors, a paint splattered tablecloth protecting the oak. Arguably, wildly delicious borscht was the highlight of the menu. Helen Harrison, director for the house and study center, led a tour up the stairs to a room used by Krasner as a painting space for a decade, with its view to Accabonac Creek. As a survival tactic for her marriage, Lee, who could not cook, learned the recipes of Jackson’s mother, Stella Mae McClure Pollock, and entertained friends with him on that inspiring site.
