I think you should.

Don't pour it into boiling stuff (I'm thinking you probably didn't). But for those who don't know... you don't really want to boil things like tapioca and arrowroot... just put it into lukewarm 'gravy' and then heat it enough to thicken your sauce to where you want it. I work with arrowroot a lot and it will turn into 'snot' (sorry ) if it gets too hot. (sorry again! )
