If anyone living in NorCal, and know whether I can buy Annatto
(Achiote) paste.

I want to use it as coloring (in tandoori chicken; see Vah-Chef's
video on youtube) or flavoring in light frying of chicken.


No, I do not want to use red color or yellow color.

I am very familiar with saffron. We used it in Biriyani (similar to
Bengal Style) - hired a chef who cook for us as only chef can cook
such a dish. Search for a video on youtube if you are interseted in.
Do not be mistaken as Biriyani of other Indian state.

The other day, I put a little saffron in tandoori marinade; I got that
saffron when buying Tilda Basmati rice in another state.

What is the cheapest brand of saffron - I am referring to the real
saffron, not the colorant?
