I was kidding when I said it had to be 100% artificial. The main idea is that all the ingredients should be very easy to obtain and the production process should also be very simple. Yes, of course, this is exactly what was done in the days before the Bottled in Bond and Pure Food and Drug Acts, and also during Prohibition. Prune juice is another classic ingredient I had forgotten. It bears repeating that there is no point to this. It's just a goof.
