The original recipe is on the first page so I'm giving this a go now with the red onions in the base and the 'soapy onion' mixture for later (I hope this is worth it as it has taken about 2 hours to get to the 'bread dough' stage).

Definitely reminds me of the KD base but I wonder if the pre-fried tomato stage is key here.  Look at the recent posts by Dragon who owns a restaurant ... he swears by using Tomato Frito (fried tomatoes !!!).

PS I ground up some cinnamon stick - smells 10X better than an old jar of ground stuff I had in the spice cupboard so I'll let you know how this turns out later.

Did you use red onions  ?

I'm a bit confused with the recipe for the final dish (say a madras). Do you need to cook a 'medium chicken curry' first and then make a madras out of it or can you go straigt from base sauce and cooked chiken to the final dish ?
