Pâte à Chou

In a heavy saucepan bring water to a boil with butter and salt over high heat. Reduce heat to moderate. Add flour all at once and beat with a wooden spoon until mixture pulls away from sides of pan, forming a dough

Transfer dough to bowl of a standing electric mixer and beat in 4 eggs, 1 at a time, on high speed, beating well after each addition. Batter should be stiff enough to just hold soft peaks and fall softly from a spoon. If batter is too stiff, in a small bowl beat remaining 2 eggs lightly, 1 at a time, and add to batter, a little at a time, beating on high speed, until batter is desired consistency.
