I was browsing around on the Mortons and I came across this information that I thought might come in handy.
Which Morton Salt products are gluten-free?http://www.mortonsalt.com/faqs/food_salt_faq.html#q2
Please be assured that the following Morton® products are gluten free:• Iodized Table Salt• Plain Table Salt • Coarse Kosher Salt• Sea Salt (Fine and Coarse)• Salt Substitute• Lite Salt™ Mixture• Salt & Pepper Shakers• Canning & Pickling Salt• Popcorn Salt• Nature’s Seasons® Seasoning Blend • Hot Salt™• Seasoned Salt• Garlic Salt• Sausage & Meat Loaf Seasoning• Tender Quick® • Sugar Cure® (Plain) • Smoke Flavored Sugar Cure®
Then when I saw Seasoned Salt in the list, it made me think to check the brand I have in my pantry which is Lawry's Seasoned Salt. Their website did not say but after browsing a bit around the internet I am pretty sure it is gluten-free. Apparently, Unilever (the parent company) is one that always declares gluten sources. Funny while I was looking, I discovered a place where someone posted the ingredients in their shaker and it contained soy lecithin. That scared me for a minute because I thought I had looked pretty closely but they must have taken it out because it is not on mine. No gluten, no dairy, no soy.
