Jungle Cat: bourbon, grapefruit, pineapple, lime, cane syrup, bitters

Tasted like a less-tart more-tropical whiskey sour (which, looking at the ingredients, I guess “duh”) — my wife insists on this becoming a staple of hers this summer, best guess at recipe?

I’m assuming the bitters are ango given the color of the shaker. Please excuse the terrible photo which we took 1/3 through the drink on a bad phone — just wanted to show color, volume, serving — double old fashioned on medium rocks.
