Zusatztipps für die Zubereitung

Be sure to chill the dough well before rolling to make cutting the shamrock shapes easier and to prevent spreading while baking. Use a light dusting of flour when rolling out the dough to keep it from sticking, and handle the dough gently to maintain its buttery texture.
