Interesting, I have never used starch nor flour in an Indian curry before since reduction itself makes tomato/coconut based curries thick enough imo. I adopted the starch technique from Sichuan cuisine, particularly Mapo Tofu (replaced the meat with mushrooms) and use it for almost any sauce now because I do not like the flavor/texture of flour in sauces generally. It totally changed my cheese pasta sauce game for example. Only rule is to add the starch-water mix in small amounts to make sure not to overdose it, otherwise the sauce might get pasty.
That’s how I’d usually do it for Indian curries, but I thought the roux was a main ingredient for japanese curry.

I wouldn’t add flour or starch to an Indian curry, I meant moreso regarding relying on the onions and spice mix.
Oh, I see!
