This follows in the grand tradition of Delia Smith’s How to Cheat at Cooking. It’s one of my favourite recipe-books, partly because there’s no shame in being lazy and using ready-made ingredients like pastry. This recipe does not, specifically, come from it, but I doubt I’m the first to have made cheese puffs in this manner.
All you need for these Cheese Puffs is an amount of puff pastry (I had a half-block to use) and as much of your preferred cheese, grated, as you like (I had about 150g). I used grana padano, a parmesan-style cheese from Lidl, ready-grated because I’m lazy like that.
So, all you do is this:
Preheat your oven to 220C (200C fan).
Roll out your pastry to a sensible size (about 1cm thick: of course, there’s no reason why you shouldn’t use the ready-rolled stuff, in which case this becomes even easier) and cover half with grated cheese. Fold the other half over and roll out again. Repeat several times (probably until your oven is about ready and you’ve run out of cheese).
Chop into squares and pop on a baking tray. Bake for about 20 minutes, until golden brown.
Try not to eat them all at once!
