I have a question about the coconut milk in this recipe. My son is allergic to milk, and when I gave him some ice cream made with coconut milk it made his skin red where it touched. This was over a year ago, and I can't remember if he had hives too or not. Anyway, I was wondering if anyone knew if there could be any cross-contamination issues with canned coconut milk. I bought a real coconut and that milk was fine with him. The cans of coconut milk I have seen at the store are from foreign countries and don't list "ingredients". It was very mysterious to me. Maybe it was the cold from the ice cream he was reacting to? Any ideas?? Laurie
