Timeless pancake pals butter and syrup cozy up at Burlington’s Maple Madness fest on the Church Street Marketplace. Barre stone carver Sean Hunter Williams captivates viewers with a live butter sculpture demo at Frog Hollow Vermont Craft Gallery during the daylong syrup-centered jubilee. The transformation of a hunk o’ hard cream into a temporary work of art is an unexpected departure from Williams’ usual — and quite permanent — medium of granite, but he brings all his precision and technique to the task. So, why use butter? In keeping with the day’s theme of agricultural heritage, Williams’ choice is a deliberate nod to dairy, yet another important Green Mountain industry.
