For best results, use a stand mixer with a dough hook attachment for kneading. If the dough is too sticky, add flour 1 tablespoon at a time until it reaches the right consistency.

Brush with milk and sprinkle with coarse sugar before baking for added sparkle and sweetness. Add lemon or orange zest for a citrus twist
