I'm sorry Abdul hasn't posted for so long, he's a great help
I dug out his Learn 2 Cook book and made the gravy from it
After cooking it I left it to "mature" in an old ice cream container, for a week, in my fridge
I have just made a Korma sauce, using this gravy
And honestly folks, I can't recommend it highly enough
I cooked on the "wok" part of my gas cooker, and left the pan on high heat to evaporate the sauce
This gravy is particularly thin
I got an absolutely fantastic result
I served it with freshly fried chips
