I nearly went wrong with the foil parcel. Jamie says 'tear off four arm-length pieces of tinfoil and fold each in half to give you four A3 sized pieces of foil'. Now, I was using my husband's arm as a vague measure, but even so, once folded, the paper was A4 not A3. I think. (Paper sizes are confusing: I have always found the fact that A3 is bigger than A4 off-putting). Anyway I simply didn't fold the foil I had cut, but cut another piece the same size and managed the double thickness that way; it worked fine.
I also nearly had a query about the amount of butter stuffed into the shanks - 150g for four. Which would mean about 75g for two. Which is a lot of butter. However, this sort of cooking isn't an exact sort of science, like baking; it allows for a bit of experimentation (or so I think). So I just made up the amount of butter that looked sensible for my two shanks but didn't make me fear for our arteries. I'm definitely not a member of the food police (you know, these people who go on and on about salt and fat, amongst other things - and usually live on those horrid artificial cardboard ready meals that promise reduced salt, low fat, no flavour...) and I didn't weigh my butter; I just used what looked right for my shanks.
Mmm. Baking the shanks in foil with white wine means that they sort of braise and bake at the same time; they are both beautifully tender and deliciously sticky round the bone like roasted meat, so you get the best of both worlds. And the flavour of the meat really does, as Jamie promises, come out here. He suggests serving this for a dinner party and I think it would be a fab meal for friends - these rustic parcels would be fantastic at the table, simply served with mash and greens, not least because after you've made up the parcels then you're free to leave them to bake for ages so you don't have that last-minute 'guests-are-here-and-I-need-to-talk-to-them-but-what-if-I-burn-the-dinner' moment. (I have those a lot. I tend to be over-ambitious, not because dishes are difficult but because there is a lot of last-minute fussing, and then I have a drink and talk too much and everyone's got a slightly well done dinner).
I served this with mash and peas (no peas on the photo; Simon took it before we had plated up the peas)
Autumn comfort food. Yum.
