<<Disclaimer: Verify this information before applying it to your situation.>> I buy Bakers and Chefs Aged Cheddar Cheese Sauce at Sam's Club. It is about $5.50 for a 1 gallon can, which I then put in quart containers and freeze. I use it in omelets and nachos. It is produced by Associated Milk Producers, INC. at 315 N. Broadway, PO Box 455, New Ulm, MN 56073. Phone # 507-354-8295. What follows is a letter I received from Michael A. Stark of that organization. Our cheese sauces and puddings reportedly contain no gluten. The annatto coloring agent used is from the annatto seed. Our modified food starch is corn based. The natural flavors used are all vegetable based. The vinegar (fermented alcohol) is derived from starches from which all gluten has been removed. Michelle in Anchorage, Alaska, USA
