How To Make Classic Chocolate Eclairs
Preheat the oven to 450 degrees F (230 degrees C). Grease a cookie sheet; set aside.
Make choux pastry: Combine water and butter in a medium pot. Bring to a boil, stirring until butter melts completely. Reduce heat to low; add flour and salt. Stir vigorously until mixture leaves the sides of the pan and begins to form a stiff ball. Remove from heat.
Add eggs, one at a time, beating well after each addition until incorporated. Using a spoon or pastry bag fitted with a No. 10 or larger tip, spoon or pipe dough onto the prepared cookie sheet in 1 1/2×4-inch strips.
Bake in the preheated oven for 15 minutes. Reduce heat to 325 degrees F (165 degrees C) and continue baking until the bottoms sound hollow when lightly tapped, about 20 more minutes. Cool completely on a wire rack.
