Stir with ice, strain into Nick & Nora glass.
A very simple cocktail that doesn't require any adornment. This was a natural combination: passion fruit liqueur's distinctive flavor, some sweetness with mellow ancho flavor and spicy heat, plus the vanilla of the bison grass vodka.
I had an experience some years ago tent camping with small children, when a small bison herd wandered into our camp at daybreak during rut. I grew up with cattle, so keeping the bison from the kids' tent, while not riling the agitated/amorous bulls was a reasonable challenge/adventure. (Spoiler/hint: guide the curious females where you want them to go, stay well clear of the bulls.) Fortunately the more aggressive mature bulls were busy engaging one another while I conducted the bulk of the herd around the campsite.
