Here is an idea for a Christmas centerpiece that can be as humbly simple or as lavishly extravagant as you wish. As an artist that works with food, I choose ingredients that look like the things we find in the natural world, but smaller. So a broccoli spear is a tree, cauliflowers become clouds and, as seen in this recipe, rosemary sprigs turn to pine trees. For this particular make-at-home version of a snowy winter wonderland, I have created a Christmas Tree with sprigs of rosemary as foliage, and an assortment of edible treats for the baubles and gifts under the tree. -- Carl Warner
