How do you intend cooking them Caze?
I cooked them on a pizza stone in the oven at it's highest temp (it was on for nearly 2 hours before they went in), unfortunately I don't think my oven is quite good enough to get these exactly right, it only goes to 230c.
They turned out a lot better than my previous efforts, but they were still some way off resteraunt quality.
The main improvements were with the softness, but ideally you should have a uniform softness, mine were a bit overcooked and hard on the outside, but quite nicely done inside. I'm sure this was solely down to my oven temperature, I might try switching the grill on once the oven is fully heated the next time (I've a couple of them in the freezer so will try again in a few days). I'd never heard the water-sprinkling trick before, and that definitely helped create some blisters, but as it wasn't hot enough so they didn't brown enough.
The taste was also not quite there, it was close though. This could well have been down to the fact that I used a lot less of the milk-egg mixture in the end, the next time I might use more of that mixture and less of the water.
I was also surprised by the lack of yoghurt, most recipes seem to use it, so that could have effected the taste as well.
