Take some of the guesswork out of the shopping search--use this list to find flour alternatives.

Potato Starch Flour

This is a gluten-free thickening agent that is perfect for cream-based soups and sauces. Mix a little with water first, then substitute potato starch flour for flour in your recipe, but cut the amount in half. It can be purchased in a health food store.

Tapioca Flour

This is a light, white, very smooth flour that comes from the cassava root. It makes baked goods impart a nice chewy taste. Use it in recipes where a chewy texture would be desirable. It would work nicely in bread recipes such as white bread or French bread. It is also easily combined with cornstarch and soy flour. It can be purchased in a health food store.

Soy Flour

This nutty tasting flour has a high protein and fat content. It is best when used in combination with other flours and for baking brownies, or any baked goods with nuts or fruit. It can be purchased in a health food store.

Cornstarch

This is a refined starch that comes from corn. It is mostly used as a clear thickening agent for puddings, fruit sauces and Asian cooking. It is also used in combination with other flours for baking. It can be purchased in a health food store.

Corn Flour

This flour is milled from corn and can be blended with cornmeal to make cornbread or muffins. It is excellent for waffles or pancakes. It can be purchased in a health food store.

Cornmeal

This is ground corn that comes from either yellow or white meal. This is often combined with flours for baking. It imparts a strong corn flavor that is delicious in pancakes, waffles, or simple white cakes. It can be purchased in a health food store.

White Rice Flour

This is an excellent basic flour for gluten-free baking. It is milled from polished white rice. Because it has such a bland flavor, it is perfect for baking, as it doesn't impart any flavors. It works well with other flours. White rice flour is available in most health food stores, but also in Asian markets. At the Asian markets it is sold in different textures. The one that works the best is called fine textured white rice flour.

Brown Rice Flour

This flour comes from unpolished brown rice. It has more food value because it contains bran. Use it in breads, muffins, and cookies. It can be purchased in a health food store.

Kamut and Spelt Flours

These are ancient forms of wheat. While they aren't appropriate for gluten-free diets, they are excellent substitutes for plain wheat flour as they add wonderful flavor and consistency.

Substituting Gluten

Wheat flour contains gluten, which keeps cookies, cakes and pies from getting crumbly and falling apart. It is what makes baked goods have a good texture because it traps pockets of air. This creates a lovely airy quality that most baked goods possess when baked with traditional wheat flour. In order to help retain this structure when using non-wheat flours, gluten substitutes must be added to a gluten-free flour mixture. For each cup of gluten-free flour mix, add at least 1 teaspoon of gluten substitute. Here are three very good substitutes for gluten.

• Xanthum Gum
  
  This comes from the dried cell coat of a microorganism called Zanthomonas campestris. It is formulated in a laboratory setting. This works well as a gluten substitution in yeast breads along with other baked goods. You can purchase it in health food stores.
• Guar Gum
  
  This is a powder that comes from the seed of the plant Cyamopsis tetragonolobus. It is an excellent gluten substitute and it is available in health food stores.
• Pre-gel Starch
  
  This is an acceptable gluten substitute. It helps keep baked goods from being too crumbly. This, too can be purchased at most health food stores.

Substitution is the solution

If you are ready to try some recipes, start with recipes that use relatively small amounts of wheat flour like brownies or pancakes. These turn out lovely and the difference in taste is minimal. Here are two gluten-free flour mixtures that are suitable for substituting wheat flour cup for cup.

• Gluten-Free Flour Mixture I
  
  1/4 cup soy flour
  
  1/4 cup tapioca flour
  
  1/2 cup brown rice flour
• Gluten-Free Flour Mixture II
  
  6 cups white rice flour
  
  2 cups potato starch
  
  1 cup tapioca flour

The above mixtures can be doubled or tripled. Another option is to purchase a gluten-free flour mixture at a health food store to avoid the guesswork involved in substitutions. This flour mixture can usually substitute wheat flour cup for cup, but read the package directions to be sure. Keep these flour mixtures stored in containers at room temperature and keep them on hand to simplify your baking routine.
