I'd like to make a caramel sauce with crystalline fructose as my mom's diabetic and can't have sugar.

I know (in theory) that fructose caramelizes at a lower temp than regular sugar, but I'm not sure if caramelizing crystalline fructose would lead to a similar taste and if I should do it the same way as if I were using sugar.

Thank you v much :)

  • What did you tried so far?

    I think you should check with a doctor. I believe your premise is wrong. Diabetics need to control carbohydrates in general, not just sugar.

  • Mom's on insulin and we check in every three months with the doctor. She's had diabetes for over five years, plus a slew of other issues. So, thank you for your concern, but I'm well aware of what diabetes involves and requires. And, just for the record, the caramel sauce is for a no-bake cheesecake I've already modified to be diabetes-friendly, except that I make it with lemon curd and wanted to try something different for Xmas - namely an apple caramel cheesecake.

It won't caramelize, it doesn't have the same properties as sugar.

What you can do is brown butter, cook it with cream, and flavor it with vanilla and crystalline fructose to approximate caramel. I haven't tried this, there are a variety of "diabetic caramel sauce" recipes you can google.

  • Thank you. And I have Googled but many of those recipes use sweeteners that I can't find locally. My other idea was to try to make something like a pastry cream and flavor it with sugar-free Torani Caramel syrup. Guess I'll be going that route. Nov 13, 2018 at 8:03
