Actually 何叔 is right...Just learnt...
A fresh or frozen turkey might not be a food you would normally suspect as a source of gluten. But think again because, unfortunately, basting solutions injected in turkey during processing may contain gluten. And those handy little gravy packets included in the packaging of some brands of turkey almost always contain gluten and should be tossed.
The good news is that several of the most popular, easy to find and economical brands of whole fresh or frozen turkey are gluten-free. As always, read labels carefully and if you aren't sure about a product, contact the manufacturer before buying your Thanksgiving turkey.
