Quick answers to all points so-far raised :
1) I am assuming that Bob was referring to a proprietary enzyme-based tenderiser, so I ordered (and have now received) 2lb Badia Meat Tenderiser [1], as well as a couple of smaller packs of Rajah. Bob, I seem to recall, surmised that papaya would be too expensive for production lines such as Lahore 1
2) I wasn't phazed by the absence of a recipe in that I have eaten sufficient Lahore-style kebabs to have a reasonable idea of what goes in them.
3) The essence, to my mind, is first to create the texture (so that it sticks together on the seekh, and has the correct mouth feel), and then and only then worry about getting the spicing and other ingredients right. On this first occasion, I just used Patak's catering-size Madras Kebab paste, frequently mentioned and recommended by a former member of this forum.
4) I seem to recall that I also looked at Razor's kebab recipes, Ray being a reliable sort of chap.
5) Herself suggested that I use pineapple as a tenderiser, but I thought that the flavour would be too obvious.
6) I have e-mailed Bob, but no answer as of today.
