Juan Meyer's original recipe calls for equal parts: Redemption rye whiskey, Suze, Amaro de Montenegro, and lemon juice. It's very tasty but I couldn't...
Out of rye at the moment, so I just made this with double the bourbon and replaced the rye measure with a half-measure of a smoky single malt. Also halved the Suze (I do love it, but it's rather domineering). The result was reminiscent of a boozy whisky marmalade - very nice, it'll do until I get a restock!
