When I got my latest curry gravy sample, I froze a portion of it.
Accidentally, I got some of the oil on my hands
My fingers stunk for two days after (and I do wash my hands!)
It's really very strong stuff
They boil their gravy for hours before skimming the oil.
One interesting thing was mentioned
When I asked for the sample, they said "do you want it heated?"
That infers that the curry gravy sits cold on the stove
It's probably, a myth from my Pat Chapman books, but I thought it bubbled away all evening
