You will end up with extra egg mixture. I poured the extra mixture into 3 pyrex custard cups and steamed in the oven at the same time. To steam the custard place cups in a baking pan half filled with water. Place in the oven and bake about 50 minutes or until center is set and tester comes out clean. You may have to add water more water to the baking pan during cooking, do not let the pan get dry, it may burn your custard. The custard is yummy! You can use this recipe to make just the custard!
