Spelt is similar to wheat in appearance. However, spelt has a tougher husk than wheat, which may help protect the nutrients in spelt. Spelt flour has a somewhat nuttier and slightly sweeter flavor than whole wheat flour. Spelt contains more protein than wheat, and the protein in spelt is easier to digest. This means that some people who are allergic to wheat may be able to tolerate spelt. Spelt has gluten, just like wheat, so spelt is not suitable for a gluten-free diet.
Spelt flour can replace whole wheat flour or whole grain flour in recipes for breads and pasta. Some people like to blend spelt flour with wheat flour, although you can use spelt to replace wheat in almost any recipe.
