It's quite simply, hazelnuts that have been ground into a meal. The nature of nut flours is such that you get some very fine pieces and some slightly larger pieces. Hazelnut meal is a gluten free flour with no real starch of which to speak. Whole grains are composed of three parts, one of which is primarily starch and protein (endosperm). This piece of the grain is what comprises white flour. Nuts are a whole different story. They have a considerably lower proportion of carbohydrates and starch than a grain does. Making them great for low carb diets, but not so great for baking in the way that we typically think of it.
