CA, that's the video that I mentioned earlier, its very impressive, This is what Ray is describing?
Going on texture of the Keema found in the Naan's i've had, I would say that it has been ground in a processor. It certainly doesn't resemble mince. Next time I try my recipe anyway, I will try using the Chana Dal instead of the flour.
One of the tips on VahRehVah (Shami Kebab Recipe) is to use chunks of lamb. Being careful not to over blend, you should end up with a mixture with a fibrous texture.
In terms of making sure it's dry, I refer to CA's comment on breaking his Pizza stone due to the oil's from the Keema leaking out. Keeping in mind of course, my recipe was meant to be for Shami.
