This savory custard features creamy Gorgonzola and the sweet succulence of leeks. Let it precede an entrée of barbecued steak or duck breast for a guest dinner. You can assemble it in advance and bake at the last minute, or bake it ahead and reheat to serve. Finish the dishes with Parmesan cheese for a sharp bite, or sugar for a sweet touch.
Due to the moisture content of brown sugar, it recommended to dry it before caramelizing. Spread light or dark brown sugar out on a baking sheet in a 1/8-inch layer and bake in a preheated 275°F oven for 8 to 10 minutes, or until browned a shade darker. Let cool, place in a small resealable plastic bag, and crush it thoroughly with a rolling pin or flat metal mallet to make fine crystals. Brown sugar treated in this manner has an excellent flavor when caramelized.
