My husband is a new celiac and I am learning to cook all over again....I asked the health food store for potato starch flour, used in so many recipes and they said I had to order a case as they didnt sell much. What I got was potato flour. :angry: I need to know if it can be converted to potato starch flour by adding something such as corn starch?

This is new for me too, I am a willing supporter and want to do this right. Any help is appreciated!

Thanks

Joy

I have never tried to convert potato flour by adding anything to make it more strachy. But i have used potato flour as a straight across replacement for potato starch in some things. In dryer applications like cookies, starch or flour can be used, usually without any problems. In moist applications like cakes, potato flour is heavier and can make a cake a more dense.

You can order these things on-line if you can't get them locally, and depending on who you order from, shipping isn't that bad. kinnikinnick.com is a really good one and they have some pretty good pre-made foods too. They ship for a flat rate of 10$ no matter how much you buy.

Hope this helps a little...

I asked that same question a few months back. The health food store said it was the same thing. NOT TRUE. when a recipie calls for potatoe starch flour, what you want is potatoe starch. In my little experience, most recipes will say potaoe starch and note not flour. Potatoe flour is usually used in very small amounts, starch is used in larger quantities. You cannot convert the two. they are two different things.

I find when you make things with potato startch like cookies.. they are thin runny and flat.. but when you use potato flour they hold together better. So go ahead and substitute the potato flour, and if you can get it use like half tapioca startch or cornstartch

It's a grand experiement and you will find the right combinations that work for you!

I should have mentioned earlier that when I substitute potato flour for starch in a cookie recipe, there is usually a combination of flours, as it is in most gluten-free baking. When I make cookies I will usually use about 1/2 rice flour and a quarter each of tapioca and potato, and in this case I can turn out some really good cookies.

When you use something like potato flour in a cookie recipe that calls for potato starch, you might try increasing the temperature to set the structure of the cookie, before it goes flat. Sugar can make a difference too. Granulated sugar will melt, but powdered sugar will not. So if you are having trouble will flat cookies, if you substitute 1/4 of the granulated sugar for powdered, they will spread less.

Good Luck! And DLayman is right, when you expirement, the best gift is finding the formula that works for you.

You can find potato starch flour in most regular grocery stores in the Kosher section.

The difference between Potato Flour & Potato Starch?

Potato Flour is cooked potato that is dried and then powdered. It is the equivalent to dehydrated mashed potatoes, to which you add water. It is not in the recipe to act like or replace traditional flour. It smells/tastes like potato, because it is potato.

Potato Starch is the carbohydrate from the plant cell that is dissolved in hot water, dried and powdered. An equivalent is cornstarch. This is a non-gluten flour that is in the recipe to act like or replace traditional flour. It is odourless and tasteless.

Problems occur when Potato starch is called Potato Starch Flour. Because it is a mixture of both names, most of the time you will need to check the label of the substance you are purchasing: potato starch says "potato starch" on the nutritional label under ingredients.

The sweet potato "flour" is just the ground fibres of the root: of little nutritional value as it has been thoroughly washed to extract the starch. To be the equivalent to commercial potato flour, you would have to cook, dry and powder it.

My cookie flour mix is 5 c wht rice flour, 2-1/2 c potato flour (not starch) and 1-1/2 c tapioca flour. Ran out of potato flour; can potato starch be used instead? Live 1 hr from a store that may carry it and we've been without cookies for 2 weeks! My husband and I are having "cookie attacks"! Thanks!

FInd an Oriental market. In Japanese a very good potato starch is called katakuriko. clear plastic bag about 3 x 7 inches showing the white powder inside. # big blue Japanese characters on the fruit. Works way better than any corn starch.

      Draft gluten-free ciders… can they be trusted ?

      By Rejoicephd · Posted

      That and my nutritionist also said that drinking cider is one of the worst drink choices for me, given that I have candida overgrowth.  She said the combination of the alcohol and sugar would be very likely to worsen my candida problem.  She suggested that if I drink, I go for clear vodka, either neat or with a splash of cranberry.   So in summary, I am giving ciders a rest.  Whether it's a gluten risk or sugars and yeast overgrowth, its just not worth it.

      Tea Bags and Gluten

      By Scott Adams · Posted

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      Inconclusive results

      By Scott Adams · Posted

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.

      Medication

      By Scott Adams · Posted

      Welcome to the community! Generally, for a gluten challenge before celiac disease blood tests, Tylenol (acetaminophen) is considered safe and should not interfere with your antibody results. The medications you typically need to avoid are those like ibuprofen (Advil, Motrin) or naproxen (Aleve) that can cause intestinal irritation, which could potentially complicate the interpretation of an endoscopy if you were to have one. However, it is absolutely crucial that you confirm this with either your gastroenterologist or your surgeon before your procedure. They know the specifics of your case and can give you the definitive green light, ensuring your surgery is comfortable and your celiac testing remains accurate. Best of luck with your surgery tomorrow
