I have an Indian recipe that calls for mustard oil, but when I went to my local Indian grocery, all of the mustard oil (with the exception of the mustard FLAVORED oil) said For external use only. What should I do? Is this just something put on the label to appease the FDA and people still eat this all the time? Can someone recommend a brand of edible mustard oil? I have to use a cup of the stuff! Should I use the "flavored" stuff?
