<<Disclaimer: Verify this information before applying it to your situation.>> Hi loop, I have a cake recipe that calls for 2 and 1/2 tsp. of guar gum and I ONLY have xanthan gum on hand. Are they interchangeable and can I just substitute xanthan gum in equal amounts? I tried searching the archives this evening but the site must be down. Thanks for any help....
