Blend together the egg whites, eggs, flour, milk, sugar, vanilla, and salt until smooth. Melt butter in a 10to 12-inch nonstick ovenproof frying pan in a 425 degree oven. Tilt the pan to coat it evenly. Pour the batter into the pan and bake until puffy and well-browned (about 25 minutes). In a bowl, combine the berries and cinnamon. Spoon the misture onto the dutch baby and sprinkle with powdered sugar. (4 servings) Submitted By RHOMMEL <RHOMMEL@IX.NETCOM.COM> On FRI, 24 NOV 1995 164521 ~0500
