As far as I can tell, from a cursory search of the internet, the Sour Pal is a drink recipe that I may well have invented. This drink came about when I was tasked with making something fresh with what we had on hand. On separate occasions we had procured the ingredients for a Whiskey Sour cocktail and an Old Pal. While staring down the relatively limited selection of options I went with the tried and true American approach, go big and throw it all in. As luck would have it, the result is delicious. We're calling it the Sour Pal because it is a blend of a classic Whiskey Sour and an Old Pal which itself is a riff on a Negroni. Like the Negroni it is dead simple to make since it is mostly equal parts everything, save the simple syrup and the whiskey (less of the former and more of the latter).
½ oz Simple Syrup
¾ oz Lemon Juice
¾ oz Campari
¾ oz Dry Vermouth
1 ½ oz Rye Whiskey
Add the simple syrup, lemon juice, rye whiskey, Campari, and dry vermouth into a cocktail shaker with ice and shake until well-chilled. Strain into a whisky tumbler (aka the rocks glass or the lowball) with a large ice cube. lightly twist the orange peel over your cocktail so the oils spritz into the drink. Then, drop the peel into the glass. For extra tastiness add a bing cherry as a garnish.
