Pull off the highway to eat at Eureka, a tiny fruit and berry farm a half-mile or so from the Tasmanian coast. The sign promises an array of bests—the best ice cream, the best fresh berries, and the sign doesn't lie. Eureka, it turns out, is blessed with its own perfect berry-growing climate, a little eucalyptus forest consisting mainly of blue and white gums. Here Ann and Denis Buchanan plant and harvest, and make their own jams and chutneys. Try the pudding, a tart mash of berries and bread.
