Not gonna lie, I'm not a huge fan of the rice teething crackers that fill the baby aisles these days. They're sort of flavorless, insubstantial wafers that break down into a soggy mess and, once hardened, are impossible to clean up. Years ago, I remember seeing zwieback toast packaged and marketed as teething biscuits, but after looking around, it seems that both brands I recall have discontinued the product. Bummer! But then again, perhaps not. In my online quest, I discovered many recipes for making zwieback from scratch at home. I decided to give it a try.
