Keep the puff pastry cold for the flakiest layers; if it warms up while assembling, chill the filled log for 10–15 minutes before slicing to help maintain neat rounds. A serrated knife makes cleaner cuts without squashing the roll. Swap Dijon for honey mustard for a sweeter profile or add a thin layer of caramelized onions for depth. You can assemble and refrigerate the log up to 24 hours ahead or freeze the sliced pinwheels raw; bake from frozen, adding 3–5 minutes. Serve with a grainy mustard dip, and for crisp bottoms, preheat the baking sheet in the oven before placing the pinwheels on it.
