I see here and on menus pasta dishes that have a vodka cream sauce. I drink vodka every day !!! but have never cooked with it or been served a dish with it as an ingredient. I've read that it enhances some flavors but get no elaboration on that. I cook with wine, beer and various spirits but never vodka. From what I've read, it's not used for its flavor. I just don't get it. Can someone please explain its purpose in cooking. Thanks in advance.
