You should go to Pinterest and join if you have not. Then put in a search for Gluten Free Key Lime Pie. Also list diabetic. Several should pop up, then you can check them out and pick one. There are so many good recipe links here.
Thanks. I try to avoid social media (I think!) so unless I get really desperate, I don't think I'll join. But I appreciate knowing that.
What I've thought about doing is using evaporated milk (instead of sweetened condensed milk) and a tiny amount of sugar. I can add a likewise reduced amount of sugar to the heavy cream for the topping (whipped). I'm googgling the two types of milk now, and they may actually not be interchangeable, so I'll need to read more. The final trick after that will be the crust. There are plenty of gluten-free crusts but as most of us know, for bread products, sugar is often increased to disguise the fact that it doesn't taste as good (in my opinion!).
