Thanks to Dan's advice my bottle of Bonal is comfortable resting in my fridge. However, before it put it in I had to try a few experiments.
My first go was the Now Voyager (link), a creation of none other than the inimitable Rafa
1 Oz Jamaican Rum (Smith & Cross)
1 Oz Rhum Agricole (La Favorite Blanc-also a new purchase)
1 Oz Bonal
2 ds Xocoatl Mole Bitters
Stir, strain, up, lemon twist (discard)
Fantastic drink, lovely rich deep flavors. The combo of chocolate bitters and the Bonal is a great one.
To find out how Bonal worked in a sour application, I also tried Ted Kilgore's Word to the Wise (link)
1 Oz OGD 114 Bourbon (Wild Turkey 101)
0.5 Oz Bonal
0.5 Oz Green Chartreuse
0.5 Oz Maraschino
0.5 Oz Lime Juice
Shake, strain, up, cherry(omitted)
Perhaps a touch sweet, but very nice flavor combo. The Chartreuse, Maraschino, and lime puts me in mind of a Last Word, but with the extra herbal notes from the Bonal it is more complex - less refreshing but more contemplative.
I am loving the Bonal so far. I was a little worried when I tasted it at room temperature, as it had a bit of an aftertaste. But chilled or in cocktails it is very lovely.
