I think it's an American consensus that any dish covered with cheese is better. Steamed broccoli drowned in bright yellow processed cheese comes to mind. But what dinner table in America is without scalloped or gratinéed potatoes? Too bad we Americans can't claim the idea as our own invention. The French came up with gratiné, the method of topping ingredients with breadcrumbs, butter, and cheese and baking under a broiler. Potatoes are the most popular cooked in this method, but other vegetables also deserve this special treatment. Cucumbers, a vegetable that really never gets cooked, make the perfect gratiné.
Why cucumbers? In Mastering the Art of French Cooking, Julia Child offers up her recipe for baked cucumbers and in Julie & Julia, Julie Powell discovers the deliciousness of Julia's baked cucumbers. While reading these books in anticipation of the movie, I couldn't keep cucumbers out of my mind. I just was unable to fathom cooked or baked cucumbers. Then on an episode of Julia and Jacques on PBS, I saw Jacques Pépin sauté cucumbers to serve alongside fish. So I had to try preparing something with cucumbers for myself.
