These are lovely cookies, tasting of pure hazelnut and butter, with no vanilla, cinnamon or other flavors to get in the way. (I do like vanilla and cinnamon in other things.) I used my food processor to chop the hazelnuts and also to mix the dough, so it was very easy. The dough was very soft - which worried me a little - but after spending the night in the refrigerator, it was quite easy to roll out and bake. The cookies spread a little, but generally held the cutout shapes. Thank you very much for posting this wonderful recipe.
