Jerry,
I shall wait eagerly of the outcome using Achmal's spice mix in the base, as disccused before I think experimenting with the blend of whole spices can certainly add an extra depth to the taste in the base which will naturally echo through to the final dish.
On a different note, believe it or not I haven't actually tested this base with a Madras as yet! i was wondering what you variation on CK's madras is as I wouldn't mind giving it a go! ;D
Cheers
Del
