What flour is used to make chocolate eclairs?

Here's why:

* Pastry flour has a lower protein content than all-purpose flour, which results in a lighter, more tender dough. This is important for eclairs because the dough needs to rise and puff up in the oven.

* Cake flour is very similar to pastry flour, with a lower protein content than all-purpose flour. It also has a fine texture, which is important for achieving a smooth and delicate pastry.

* All-purpose flour can be used in a pinch, but the eclairs may be slightly tougher.

Ultimately, the best flour for your eclairs will depend on your personal preference and the specific recipe you are using.
