<<Disclaimer: Verify this information before applying it to your situation.>> I would like to share with the celiac community a disaster I experienced recently with making gluten free flour mix. I purchased what I thought was potatoe starch and made up 24 lbs. of G.F. mix and 40 bread recipes. I began having trouble with the bread not coming out right and my pancakes requiring way too much milk to make a usable batter that couldn't then be cooked enough to keep the middle of the pancakes from being gooey. After a frustrating morning of failures, I began investigating my ing redients. The oriental food store packaging was clearly labeled potatoe starch but after taking a spoonful of the yellow tinged powder (instead of the usual bright white powder of starch) and mixing with a little water I discovered I had a ball of paste, I found an old box of white potatoe starch, mixed it with water and noticed the dramatic differences in the mixture. I had potatoe flour in all my mixes and that was the problem. Just want to let others know of the potential problem. Look for the bright white color for potatoe starch, you can't beat the price of the oriental markets, but beware of the english word translations for foreign products.
