Preheat oven to 425 degrees. Place the water-milk mixture in a saucepan and add the salt, sugar and butter. Bring slowly to a boil, then remove from the heat and add all the flour at one time. Beat the dough well with a wooden spoon, replace the saucepan back onto the heat, and beat the dough for 1 minute or until it comes away from the sides of the pan and no longer sticks to the spoon. Transfer the dough to a warmed mixing bowl. Add a third of the beaten eggs, beating the dough all the while with the spoon. When the egg is mixed in, add half the remaining egg, still beating the dough; finally, add the remaining egg and continue to beat until the dough is smooth. Baking: Fill the pastry bag with the dough. Butter and flour the baking sheets or line them with waxed paper. Dust the pieces of dough lightly with 10x sugar so that their shapes will be more even after baking. Bake as soon as dough is ready. Bake each sheet at 425 degrees for 15 minutes; then lower the heat to 400 degrees for another 15 minutes. The change in temperature will prevent the puffs from cracking open; but be sure to keep the oven door ajar with a spoon. Small puffs bake faster than larger ones. To Store: The puffs can be kept a week in plastic bags in the refrigerator. They can be kept one month in the freezer, but be sure to defrost frozen puffs for 24 hours in the refrigerator before using. Vanilla Pastry Cream For Cream Puffs: Place the milk and vanilla bean in a saucepan and bring to a boil. Cover and keep hot. With a wire whip beat the sugar and egg yolks together, until the mixture whitens and forms a ribbon; then gently stir in the cornstarch with the whip. Strain out the vanilla bean and pour the hot milk into the egg and sugar mixture, beating all the while with the wire whip. Pour the mixture back into the saucepan and bring to a boil again, stirring constantly with the whip, so the cream does not stick to the bottom of the saucepan. Boil for 1 minute, stirring well. Then pour mixture into a bowl and lightly rub the surface of the cream with a lump of butter to keep a skim from forming as it cools. Chocolate Icing For Eclairs: Sift the sugar. Heat the chocolate in a double boiler until melted. Then add the 10x sugar and the butter, cut into pieces. Stir until smooth, then remove the saucepan from the heat and add the water, one tablespoon at a time, to cool the mixture. This icing must be lukewarm to ice the eclairs, or used for a cake. If it is too hot, it will run off; if too cold, it will not spread very easily. Posted to recipelu-digest Volume 01 Number 457 by "Diane Geary." on Jan 5, 1998
