Chocolate Appam is a delightful twist to the traditional appam recipe. It is made with a fermented rice batter and a chocolatey filling. The batter is prepared by soaking rice and fenugreek seeds overnight, grinding it into a smooth paste, and fermenting it for a few hours. The fermented batter is then poured into a special appam pan, and a spoonful of chocolate filling is added to the center of each appam. The appams are cooked until the edges turn crispy and the chocolate filling is melted and gooey. Serve these indulgent chocolate appams as a dessert or a special treat.
