This recipe converts America’s favorite cookie, the chocolate chip cookie, into a gluten-free version.

More and more Americans are discovering they have a sensitivity to gluten, a protein in wheat and other popular grains such as barley and rye. A more serious manifestation is celiac disease.

Some of the best brands of gluten-free cookies we’ve tried are the result of a family member seeking to make the tastiest treats for a relative with gluten sensitivity. If you have a loved one who needs to avoid gluten, bake a batch of these as a gift.

There are more than 20 gluten-free or low-gluten alternatives to wheat flour, from familiar ingredients such as cornmeal and potato flour to amaranth and teff flours. They’re more expensive than wheat flour, which is why gluten-free baked goods, pasta, etc. are costlier than conventional products.

The substitutes vary widely in their flavor and texture contribution. People working on gluten-free recipes do a lot of experimenting to find the ingredients and proportions they like best.

TRIVIA: “Gluten” is the Latin word for glue. The protein acts as a binder to give elasticity to dough and a chewy texture to the final product.
