Keep the puff pastry cold for cleaner cuts and better puff; if it softens, chill the filled log for 10–15 minutes before slicing. Squeeze excess moisture from spinach if using frozen to prevent soggy centers. Vary cheeses with cheddar or Gruyère, and add herbs like dill or parsley for freshness. For advance prep, assemble the log, wrap, and refrigerate up to 24 hours or freeze; slice from partially frozen for neat rounds and add 2–3 minutes to bake time. Serve warm with a tangy dip like ranch or honey mustard, and store leftovers in the fridge, reheating in a 350°F oven to re-crisp.
