Potato Flour attracts and holds water, producing moist yeast bread with a good shelf life. A teaspoon or so added to your baked goods lends a moist crumb, so it is especially useful in gluten free baking. Potato flour also works great in pancake and waffle recipes.

Recap:

1. Preheat your oven to the lowest possible temp.
2. Wash your sweet potatoes and slice them as thin as you can get.
3. Place the slices on a crumpled piece of aluminum foil and pop into the oven.
4. Allow the sweet potato to dehydrate for 5-8 hours, flipping the slices every 2 hours.

The best substitute for potato flour overall are potato flakes, but there are other good foods to substitute by use, including corn starch, tapioca starch or flour, arrowroot powder, mashed potatoes, all-purpose flour, rice flour, and quinoa flour.

What makes potato flour such a good item is its moisture retaining properties which results in very soft and moist bread and the like. This certain type of flour lasts for about 6-8 months in the pantry.

If stored at cool room temperature, plan to use flours by the “best by” date or within 3 months after the “sell by” date. Or, you can keep them for at least 6 months in the fridge or a year in the freezer. For longer storage, keep white flours in the refrigerator in an airtight container. …

The easiest way to keep your flour fresh and prevent little bugs from getting in is to transfer your flour to an airtight plastic or glass container. “Bugs love food, especially healthy whole grain foods, and if they can find a way in, they’re going for it!” says Chef Sarah House of Bob’s Red Mill.

But remember that flour, like a lot of other baking products, usually has a best before date and not a use by date or expiration date….Flour Expiration Date.

Never mix old flour with new flour. Wholemeal flour keeps less well than white flour as the oils from the germ and bran can become rancid with age. Wholemeal flour will normally keep for about three months while white flour will be OK to use for six to nine months.

Different Types of Flour and Their Shelf Life

Spoiled flour develops an unpleasant, off odor and bitter flavor. Flour stored in warm, damp conditions will expire more quickly than flour stored in a cool, dark pantry. The moisture encourages the growth of mold, which is what usually causes the flour to have that musty odor.
