fresh tumeric accually has some aroma and flavor which can alter the flavor of your milk\cheese. so... its not just a colorant (curcumin) spice as some people tend to think, given that they likely know the beyond expiried powdered tumeric sold in shops not the fresh stuff.
I haven't done any coloring yet, but I am curious what type of cheese you colored with Turmeric. You probably haven't used enough to notice the taste, but I'm curious if there's a cheese that couldn't be complimented and colored by turmeric.
Merlot wine.
