Had this in the evening watching a concert. Yes, there are a lot of ingredients, but they all add a unique flavours and hints to the cocktail. The salt is great as it enhances the end of each sip.
I really liked this. It has depth and complexity. I used Frangelico, as I had no walnut liqueur, and added walnut bitters. Thank you, Simon - a new favourite.
Made again last night and it has really grown on me, deep and complex and definitely different, it is unique and I really enjoy the coffee and nut tones. I've been pondering the addition of either walnut or orange bitters, but for now it's a very good recipe.
