On a whim I made this with Bacardi Carta Blanca - but having no Sexy Bitters I used The Bitter Truth's Tonic Bitters, lemon zest and 10 ml 2:1 syrup (as per their bitters recipe booklet). Surpassed my expectations- although would knock the 2:1 down to 5ml. The tonic bitters are a winner -there is a hint of green tea following the citrus forward profile.
Made with Johnnie Walker Black Label - like John H. I lightened up the maple slightly - the slight pettiness of the Black Label works well with other ingredients. Impressive drink.
On my all time favourites list- the Licor 43 is so sweet it doesn't warrant 5ml of rich syrup- maybe just a dash. Great to experiment with different bitters.
