I tried it once. ONCE!!! It is disgusting. Took me all day and night to get that taste out of my mouth. Even pulling with VCO couldn't get that taste out. It made me feel so sick I tossed it out. Couldn't even bring myself to cook with it.
I bought mustard seed oil once to and have only pulled with it once or twice. Really strong taste also. Didn't like it at all. It is still sitting in the cupboard. Haven't been able to cook with that one yet either.
