<<Disclaimer: Verify this information before applying it to your situation.>> This is a relatively "new" sauce that goes with their Chicken Selects. I eat these as I'm not Celiac, but wondered if the sauce was okay for my son (I make chicken nuggets for him at home and was looking for an easy dipping sauce for school lunches). It isn't currently listed on the McDonald's GF products listing, so I asked. Here's their response: Thank you for taking the time to contact McDonald's. We always enjoy hearing from our loyal customers. I am sorry for any confusion you have experienced with our gluten free menu. For the most up-to-date information on our tangy honey mustard sauce, please visit our website at http://app.mcdonalds.com/bagamcmeal?process=item&itemID=10121. As you can see, our Tangy Honey mustard sauce is gluten free. Please be assured that I have shared your comments with our Menu Mangament team. I am certain they will appreciate you feedback. ******** I don't know if the link will work correctly as copied but you can always type it in. So enjoy...you can buy extra packets for future use, you know. Joy *Support summarization of posts, reply to the SENDER not the CELIAC List*
