Youre right ole chap, the most expensive spice in the world (or atleast one of the most) its probably more expensive than gold by weight...
I would guess this recipe is from an english or european trying to recreate a curry paste.. and mistaking turmeric for saffron.. there is a reason why saffron is sold in so small amounts and thats because its very strong stuff (expensive too).. although saffron which is cooked over a long period loses its flavour (so i recall).
Saffron is used in swedish buns at certain times of the year and you only need a little. Actually, thinking about it, the actual spice is dangerous to animals.. and i would imgine poisonous to humans in large quantities.
Many years ago i arrived in Sweden to be with my "as to be" wife. Got myself on the the langauge course and got a part time job in a bakery (cleaning). The job was straight forward and not at all demanding language wise, one day one of the bakers came over and showed me a large jar of saffron, how much do you think that costs to buy? I cant remember my answer, but i remember it was a silly price and i presume he bought it trade and still well below marked price.
So i wouldnt recommend anyone actually try this curry paste, but a variation might well work. Btw, saffron is used in kashmiri cooking isnt it?
