Okay, well, not everything, exactly. The bit about making it out of flour and butter is pretty important. And water. I'm talking about the bit where you have to get the little globs of butter just the right size — not too big, not too small — in order not to end up with pastry the consistency of damp cardboard.
So perhaps it would be more accurate to say 'forget 10% of what you know about puff pastry'. (It's a pretty crucial 10 percent. But then, I'm being mighty presumptuous about your familiarity with puff pastry, so let's all agree that the intro to this blog post is a bit of a disaster and move on, shall we?)
If, like me, you have a fraught relationship with puff pastry (the making thereof, not the eating), you'll want to read this post on Serious Eats.
I don't do butter-cutting. The practice reminds me of those depressingly interminable afternoons (double lessons) spent in Mrs Foulks' Home Economics classes, learning to make scones, or some such. She was humourless, ill-tempered and squint. (It was only after a few minutes of plodding castigation — directed squarely at the person to my left — that I'd realise she was talking to me.)
There was a lot of butter-cutting in Home Ec.
So, these days, on the odd occasion that a powerful craving for quiche hits — and a memory lapse means said craving is unobstructed by recollections of many, many failed attempts at making puff pastry — to the food processor I go.
And cock it up completely.
Usually, I forget that the desired consistency — before adding the water — is crumbly, not mashed potato.
So there I stand, at 8pm on a Wednesday night, staring in horror at a bowl of floury paste. The fact that I'm hungry and tired tips this event from the 'minor inconvenience' category into the 'this is more tragic than The English Patient' category.
What to do?
Start crying, for starters.
Perplexingly, this has no effect on the pastry.
I should have just made an omelette with the egg ingredients and called it a night, but some part of me (which I refer to as 'Scarlet' because it reminds me of that scene in Gone with the Wind when she clenches her fist and says, 'As God is my witness, I'll never be hungry again!' all tenacious-like) was determined to make quiche, even if it meant eating at 3am. So thank fuck I found the Serious Eats post titled 'The Science of Pie Dough'. It uses science (and words) to tell us why not only is the homogenous gloop outcome not the end of the world, it might actually be preferable.
All you do is add some more flour and mash it in with a spatula.
For me, this was a revelation on par with learning how to colour my own hair, or go on Facebook at work without my colleagues noticing (i.e. profound).
Of course, this could all be about as interesting to you as the annual Anglo-American fiscal report.
Use it, don't use it.
Life's too short to be cutting butter, is all I'm saying.
Oh, and someone told me I need to put the word Christmas in my post a lot if I want to get loads of hits, so... Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas, Christmas.
