Will all that fit in an ice-filled rocks glass?

In the source, it fit in a DOF, though there's not a ton of crushed ice (a gated pour would need to catch most ice). When i made it, it was barely too large for my DOF.

The volume of tiki drinks varies widely. This is large, but not the largest. A larger tiki mug would be a great vessel for this, but I noted and tried what was published.

This is complex and I think actually quite approachable. Pretty impressively balanced for the players but I suspect regular cynar would suffer. Very nice.

Used high proof Bourbon instead of blended scotch and added Peychaud's bitters with Mole bitters for chocolate and anise undertones. Poured into rock's glass with one large cube and it worked real well.

Made with Genepi instead of Chartreuse. Haters will say they're totally different but it worked very well.

Made with Forty Creek Barrel Select whisky, London Hill dry gin, and Contratto Bitter instead of the Aperol because that's all I had (it's too assertive, if you sub it then reduce the proportion). The first sip is definitely a powerful bitter punch but the sweetness of the Forty Creek shines through. I would never have believed that the drink contains no sweet liquors or vermouths! 

That absinthe brand sounds great but I only had verte and blanche at home. Used Viex Carre and was pretty good.

Is the differentiation of this vs. just a normal "rum & tonic" the clarification of it being an añejo instead of just dark rum?

The muddled mint would be an even clearer differentiator. Rum and tonic but also mojito ancestry you could say.

Adding ham as a garnish ingredient....
