Brilliant looking Madras Chinois - well done.

ps: Did you really add 1 tsp MSG - that is a lot 
(nothing a gallon of water won't cure I suppose)
I'm not convinced it has made much difference in my curries to be honest, which is why i gradualy upped the amount to 1tsp. It's not noticeable like in a packet of crisps or a dehydrating chinese. I guess they use more?
I really need to do a control experiment. The main reason i use it is that 2/3 of the restaurant kitchens i've been in use it.
If you're concerned or more sensitive to MSG then it's fine to leave it out.
