<<Disclaimer: Verify this information before applying it to your situation.>> Hi, I had great response on what people use for casein free butter/margarine. Thank you to all that responded. Here is a summary of all the responses: 7 - Fleishmann's Unsalted Margarine 6 - Shedd's Willow Run Soybean Margarine 6 - Nucoa 4 - Mother's 3 - Hain's Safflower Oil Margarine 2 - Smart Beat Spread 2 - Cold Pressed Olive Oil 1 - Winn Dixie's - Superbrand 1 - Avocado Oil 1 - Coconut Oil 1- Makes Ghee: Boil butter till white foam appears on top and then strain the white foam. Only the butter fat remains, which has been tested to be casein free. We have had good luck with this. Ghee does not have the hydrogenated oils, which makes it healthier. Also, it tastes like an intense butter flavor. It's higher in calories, but I use less of it. Recommended to check out the site - www.gfcfdiet.com Judith :o) Ottawa, Ontario - Canada
