Mustard Powder

I gotta say I am a bit of an english mustard fiend! :)

So... just thinking. if i go back to eating.. ie 790 or 1000 plan.

Can I eat Colmans English Mustard? I know that the regular mustard includes Citris Acid.. a no no... but the powdered stuff u use to make mustard with just water has only mustard flour in?

Just thought it was worth an ask?

Also... just wondered about garlic too?!
Bumping up for BBFM because I don't know! :confused:
