Now, here goes, we are going to make it:
Quickly beat your eggs together in a little jug or cup and set aside.
Step one:
Melt the butter with the water over a low flame in the saucepan. As soon as it comes to the boil turn it off, you don't want your water evaporating away.
Step two:
Tip all your flour in, in one go (I have it in a cup or jug), with one hand, while simultaniously stirring the water-butter mixture with a wooden spoon with the other. DO not stop stirring vigorously.
Step three:
Keep beating and stirring the mixture vigorously until you have a smooth ball of paste that comes away from the sides of the saucepan leaving it clean. This will not take long, a few minutes max.
Step four:
Now add the beaten eggs, slowly, a little at a time, beating thoroughly after each addition. Don't worry if suddenly you have a slimy mess with bits of the dough seperate from the egg, it doesn't matter, just add all the egg, mixing mixing mixing, and eventually all the egg will be encorporated with the paste and you should be left with a sticky silky paste.
Ta Da. Choux pastry.
