I first tried this cocktail whilst judging the Heering Classics Challenge 2018 Final and while I loved the flavours it struck me that it was just a smidgen...
Absolute cracker. Thank you. Out of circumstance I had to use a dark Creme de Cacao (Bols) and a Glenrothes 11 yr old whisky. It still retained a pleasant sweetness but you're right a great balanced cocktail. In house we're calling it a 'Naughty Camilla' but that sounds just wrong. Cheers!
