I'd like to keep the ingredients on hand for basic cocktails and drinks for company and parties. DH is always impressed when we visit someone's home and they can make pretty much whatever he thinks up. So I think he'd really appreciate a well-stocked bar.
I tried doing a websearch, and all the lists I found had at least 100 "necessary " items. I just don't believe most people own that much alcohol!
So what do you always keep on hand?
