There are plenty of things taught in culinary school that when you get in the working kitchen make you go, phfff, I can't believe they told me to do it like that at school! When you're working you see there's almost always a hundred different ways to do one job to the same end--you learn which is best for you by watching others, by playing around.
But here's something I stick by hating in school: making choux pastry by hand. Incorporating the eggs to the stiff, wet dough, one by one, till the dough was smooth and stretchy again may have given me, for a few months, the toned arms of an ambi-dexterous tennis player, and sure there was a certain satisfaction in piping it out with burning, twitchy muscles--but it hurt! And it took a long time. And kitchen aids are such wonderful things...
Unfortunately, I don't have a kitchen aid. Or a Kenwood for that matter.
And? And Glyn has been talking about eclairs for the past few days with such zest, that I've fixated on them. They're everywhere, on the fridge, at work, in every cook book I open... I can only think of a proper tea with eclairs baked that day, mmm! So? So I'm going to do what I thought I'd never have to do again, make a choux pastry by hand. Thank you Chef John and Chef Christophe, for locking away the equipment and strengthening my arms with a thousand pastry creams, genoises, choux batters, and meringues. Here goes.
Choux pastry is pretty underappreciated if you ask me. When made well, the airy golden puffs can be built into a pyramid of caramel, sliced and filled with savoury cheesy goodness or plumped up with a mixture of pastry cream, whipped cream, or butter, then iced. They will steam, rise, and brown into whatever shape you pipe or drop them. They will bake or fry, and even if you are forced to shape like ridiculous cream filled swans, they will still be tasty. Also, they're not that hard to make, and probably require no grocery shopping to get started. Plus they freeze well all piped out and unbaked if you make too much. This tray of unbaked eclairs, gougeres, and religieuses will come in handy next week, when your boyfriend's parents come to visit...So don't be scared. Flex.
Choux is a classic recipe, so there are a thousand of them out there. It's almost one part butter/flour to two parts eggs to two parts water, with slight variations of course. Today I'm testing out doing exactly this proportion as so many recipes I've seen are very nearly this proportion. Either way, they're all made basically the same way: start with a base of liquid--sometimes just water, sometimes a mixture of milk and water--my old pastry chef claimed adding milk made egg wash obsolete. I'm not sure how that works, but we did try making the dough both ways, and it's true.
When you're baking a thousand eclairs everyday for Harrods , you'll try anything to save time and skip a step. Of course, when baking one tray at home, a single step doesn't cost you a half hour but only a minute or two. But for Chef Christophe, I still replace a fifth of the water with milk and skip the eggwash. The choux gets golden without it and it doesn't add flavour so why bother? Also, I use salted kerrygold butter but still add that pinch of salt, and sometimes add about a tablespoon of sugar to flour.
240 ml water
60 ml whole milk
150 g butter
150 g flour
250-300 g whole eggs
pinch salt
Preheat the oven to 400 degrees and get your ingredients scaled out. Melt the butter and water together in a saucepan. Once boiling, whisk in the flour. Now get rid of the whisk and switch to a paddle, like a firm spatula, and keep the mass moving until it becomes a dough that holds together and doesn't stick to the sides of the pan, this should just take a couple of minutes. Take off the heat and allow to cool slightly in a large round bottomed bowl (or if you're lucky, the kitchen aid). Very gradually, beat in the eggs, waiting each time to properly emulsify the egg before adding more. Beat the crap out of it. Seriously.

You want it smooth, shiny, slightly elastic, but drippy. Confused? In French, of course, there's a term for the texture you're looking for, bec de canard. It means that if you lift the whisk, a "beak," a strand that falls in the shape of a beak will form. It looks like a duck's beak, I guess. In some cases, like if you've cooked your water/butter/flour mix for too long and too much water has evaporated, or if your flour is old and dry, you may need to add a bit more egg than the recipe calls for, to get the beak. And in some cases, you may not need to add all the egg you've scaled out, it all depends on the texture of your dough.

Eventually, you'll get there. Put the dough in a piping bag, then using a round nozzle, pipe small lines or rounds of choux onto parchment, giving them room between each other to grow. If you're egg washing for colour, and I'm certainly not, now is the time to do it. Bake for about ten minutes. They should be coloured a medium brown on the outside by now, but it's also important that you're able to pick one up and, well, check that it's bottom is golden, dry and firm--as bottoms should be. If it isn't then the pastry isn't cooked through enough and won't hold its' filling properly--just put it back in at a lower oven, 300 degrees, to dry out a bit.
Set them aside to cool, then store in an airtight container until your filling's ready and it's time to fill, which also means time to eat. If you're making eclairs yourselves, I suggest not filling and glazing until you are just about to eat them, that way the pastry stays crisp and delicious.
