It probably is not the fault of the guar gum. There is likely an acid such as vinegar to help the yeast do a better job with the gluten free flours in these recipes. Guar gum does tend to be neutralized with acid, but xanthan gum does a better job of combining starches. They both have their place in various recipes. For more information on these items check out sites such as Bob's Red Mill. They have extensive information on the usage, and amounts of these ingredients. Both guar gum and xanthan gum should be added to the oil part of the recipe to dissolve them. It makes a big difference in the final texture of the product.
This is the same recipe posted on the back of the box of potato starch. The only thing different is they add the xanthan gum 8 teaspoons into the dry ingredients, which makes it easier to just measure out. I used this blend this morning on my genetti recipe and they turned out with good results.
Last year I made pumpkin cookies with white chocolate chips in them for Thanksgiving. My mother-in-law loved them and has talked about them throughout this year. The only problem (so I thought) was that the original recipe called for white flour and she has developed a gluten intolerance. She was so disappointed that she wouldn't be able to eat them. Then I found this recipe and followed directions. Made some cookies with the gluten-free blend. They turned out fabulous! Texture, taste, etc. is perfect! Thank you for posting this!
excellent blend. this works great for cookies, cakes and all sorts of things. thank you. i've been looking for a good flour blend.
