That's a steal! I definitely paid more than that and don't regret it at all.
I've attached another picture of the Makhani sauce, in its finished (cold) state. I've omitted the julienned ginger because I use it in conjunction with the base gravy and need to keep it more flexible this way. I also skipped the green chilies because the sauce is already relatively hot. Made some test run with some mixed veg to get a feeling for the right proportions. Very, very promising so far.
