Frozen rhubarb

Can you use frozen rhubarb instead of fresh and if so, do I have to adjust liquid

using frozen rhubarb in recipes

Hi, Wendy. Yes, you can use frozen rhubarb but you should thaw it first. Also, since the frozen rhubarb will be less dense once thawed, you should use a little bit more than called for in the recipe. No need to adjust liquid.


I wish you would put nutrition facts on your recipes. I need to know the carbs. per serving for my son who is diabetic. thanks
