Egg wash was a little too thick, which might have lead to the rough edges when cutting. Crisp cookie with a rich buttery flavor and hints of citrus, in my case orange zest.
Tweaks for a cleaner cut next time:
1. Thin egg wash with milk
2. Portion dough into 1/3 and roll out thinner, 3 mm
3. Cut cookie at 3 min mark instead of 5.
