Ah! Thanks, George. Can't help but wish you happened to have said that 10" earlier... I've just got out the kitchen! Having said that, vis a vis what you were saying at the beginning of this thread, I deliberately used lamb-which of course withstands a longer cook, doesn't it. Mind you, I used pre-cooked lamb-did you too?
I'll post a pic when it's plated up, but I wish i'd thought of turning the powder into a paste: I followed the-kind of generic, I admit-bhuna in my head (probably implanted there by Mick Crawford from my earliest days on the forum!). So used the Aldi mix in place of our own spice mix, adding onions, peppers, garlic paste, other powders, chopped coriander etc, at the usual points. And, I admit, the Aldi sauce went in in three dollops, with some hot water which had "cleaned" the jar.
Pre-eating conclusions:I didn't get the caramelisation I'd usually expect to see with a normal (of course thinner) base, but on the other hand, cooking off their own spice mix at the beginning definitely smelt like the "real thing", so the sauce is looking good.
On the other hand, I grabbed the last eight of nine jars on the shelf earlier*, so I'll be doing another one-and this time I'll be following your advice there George. How long woould you suggest overall cooking time be?
(*always feel a bit bad clearing the entire shelf!)
