<<Disclaimer: Verify this information before applying it to your situation.>> Someone who knows more about Japanese cooking than I do might be able to verify or correct my following statements, but it is my knowledge that soysauce called 'tamari' is supposed to be a sauce made only from soybeans (no wheat) while 'shoyu' is a soybean/wheat soysauce. Of course, you should always read the label to be certain. I can't speak for Chun King soysauce but, when I can't get tamari at my favorite health food store, I have usually selected La Choy soysauce because it appears to be wheatfree. I say 'appears' because i haven't talked with anyone from La Choy and because their ingredients could change by the time I post this letter. Oh, the joys of being gluten intolerant! BJ
