How do I get the filling inside pâte à choux?
They are a little hard to find, but if you can find a "Bismarck" pastry tip, they have an elongated tip that is perfect for poking into your cream puff to fill. And, on a side note, a couple ways to keep your pastry tube from getting so messy... Put it inside a drinking glass and fold it down over the sides to fill it. This holds it open and you're less likely to spill all over the edges. Then, once you gather the open end, use a rubber band to tightly hold it closed. This reduces the mess dramatically.
