The jungle cat is a riff on the classic jungle bird cocktail, with aged gin taking the place of black rum in the original. Its from the caledonia spirits company, makers of tom cat gin, a rich amber-colored gin barreled in oak. Aged gin is a brilliant choice, but its the maple syrup that really ties it all together, replicating the rich flavor of the rum in the original and adding a warmth and character that perfectly highlights the unique flavor of aged gin. As in the original jungle bird, campari or another ultra-bitter citrus apritif is de rigueur. You can use aperol, of course, but it will be sweeter and a little less characterful.
