“This flan is a first course in a meal that is technically a custard with a custard sauce. Or it could just be a meal. This can be made 2 days ahead and chilled, loosely cover with plastic wrap. Bring to room temperature, then warm on an oven-proof serving platter in a preheated oven 325°F about 10 minutes. Serve with sauce. Recipe comes from Gourmet Magazine.”
