Walnut and Arbutus Honey Tart

As with all sweet pastry, speed and a cool environment are crucial to the result. By a stroke of luck I discovered that the added cornflour in the mix helps make the pastry dry, producing a better, crisper result. When baking a tart case blind, I recommend covering the pastry with cling film rather than foil or baking parchment, as these can often puncture the pastry. We get our arbutus honey from La Fromagerie, which also sells it by mail order.
