Pate a Choux (pronounced paht a shoo) is one of those pieces of kitchen magic. It is used to make an array of puffy pastries such as Eclairs and Profiteroles. A unique, double-cooked dough, Pate a Choux inflates to tremendous proportions when baked in a high temperature oven given the high ratio of eggs to flour. Surprisingly simple to execute, this recipe is worth knowing, if only for the "Wow" factor.
