The name may sound sophisticated, but the idea behind biscotti is wonderfully practical: bake the cookie twice to create its signature crisp texture. That crunch makes biscotti particularly good for dipping into coffee while also helping the cookies hold their shape beautifully. William Greenberg makes its biscotti in six varieties, including vanilla almond, cranberry almond, pistachio, chocolate pistachio, chocolate chip and chocolate dipped. They are equally suited to the breakfast table, an afternoon coffee or a gift tin destined for someone who understands that coffee deserves a proper cookie.
