Spelt is an ancient type of wheat that's native to southern Europe, where it's been used for thousands of years. It has a mellow nutty flavour and is easily digestible. Spelt has a slightly higher protein content than ordinary wheat and can be tolerated by many people with wheat intolerances. It can be substituted for ordinary wheat flour in baked goods.
Spelt is most often milled into spelt flour, which is available in health-food stores. Wholemeal spelt noodles can often be found in health-food shops too.
