My husband bought some mustard oil online through Amazon (an Indian product, Laxmi brand) for a recipe; as he was searching he noticed some descriptions saying "recommended for external use only" so he took care to find a brand that was meant for human consumption. Well the order arrived, and guess what, it states "recommended for externaluse only" - but the weird thing is that the description on the bottle (and on Amazon) extols the virtues of the "flavor" "purity" etc. etc. as though this oil IS meant to cook with. Some research suggests this warning about being for external use only is due to lack of FDA approval for mustard oil in the US, and "wink wink" it is OK to cook with. Thoughts? OK to go ahead and use this with food?
