DD,
it would be good to get your thoughts on this.
i've only made the sns once but from memory recall it to be close to the saffron. the saffron and rajver i make a lot. i feel the taste of rajver base just has the edge over the saffron. in the finished curry even side by side i can't tell any discernable difference. yet give the difference spicing between the bases u would not expect this to be so.
i find the saffron easier to shop for and prefer the reclaimed oil from it. i think the rajver suit's low spice dishes more than the saffron. for example CK's madras is better with the rajver than the saffron.
i've never really been able to decide between the 2 and therefore rotate when i want a change from the adapted CRO2.
