Everyone needs a real butter cookie once in a while. I certainly do. These cookies showcase the intense nuttiness of amaranth flour. Rolling them in minuscule amaranth seeds gives them a playful touch and adds a nice crunch, but they are also delicious without. Fine sea salt retains some of its crystalline texture during baking, adding sparks of salt to contrast the natural sweetness of the whole grain flours.
For best outcome allow the dough to chill thorougly and firm up, ideally overnight. If the dough balls become soft while you finish them with the walnuts, as in step 4, chill the baking sheet with the cookies for 20 minutes before baking.
