I disagree with the writer who said "Some drinks just take funny".
There's nothing funny about the Nasty Canasta, no sirree -- 2 parts Cobra venom, 1 part kerosene (alternate: turpentine), 1/2 part Amaro, and, of course, Liber & Co.'s awesome Pineapple Gum Syrup (to taste).
I like a lot of pineapple and skip the agave syrup, thank you very much. Instead, Liber & Co. Pineapple Syrup handles the sweetening position very well -- it is less flammable and it makes a great pineapple soda, too!
Another thing I like about gum syrup in general is the foam after a long hard shake with ice -- looks like it would make a beautiful whiskey sour and, really, who puts canned bean juice in their drink because they won't eat egg whites? Seriously? I didn't think vegans even drink alcohol ... (weirdos)
Back to the Nasty Canasta: you may have a hard time finding the recipe unless you are lucky (like me). Just don't try the recipe in the Sheriff Daffy cartoons although using a welder's mask and tongs to get it to the customer is advisable.
Here's mud in yer eye!
