When it comes to cutting lemon drop bars, the key is to use a sharp knife and slice slowly. Make sure to start with a clean knife each time, as this will help you get even slices without any mess. You can also chill the bars for about 30 minutes before slicing, which will make them easier to cut. Most importantly, make sure that you line your baking dish with parchment paper, so you can easily lift the entire thing out once it has cooled. This makes cutting even easier.
