Heat the oven to 250ºC (482°F) conventional oven, place a baking sheet on the middle shelf.
Put water and butter in a saucepan and bring to a boil.
Sift flour and add it with vigorous stirring using a whisk.
Heat the dough very thoroughly, it should be fine and glossy; use a spatula to stir.
Let the dough cool for 3 minutes and put it in a mixer with a K-padle or use a hand mixer.
Add the first egg and beat for 2 minutes. Take the spatula and scrape down the edges, add the second egg and beat for 1-2 minutes. Continue whipping the eggs in one at a time, for about 1-2 minutes each, before you add the next egg. Scrape the edge down when necessary.
Put the dough on a baking sheet lined with baking paper, using an piping bag/freezer bag or use a few spoons to make the buns.
Turn down to 200°C (392°F) conventional oven WITHOUT fan, transfer the baking paper with the buns to the hot baking sheet and bake the choux pastry for approximately 25 minutes - depending on the size. REMEMBER, DO NOT open the oven door the first 15-20 minutes of baking time, the buns will collapse!
When the choux pastry are golden and beautiful, take a bun out of the oven to test it. See if it collapses while it cools a little. If so, then bake the others a little more. If not, then they are finished.
