Unnamed as of now.

1oz white rum (Shipwreck)

1oz toasted coconut rum

1oz Heirloom Pineapple Amaro

1/2 oz lime

4 oz Jarritos Tamarind

Pretty good. Tamarind soda by itself I find meh, but its subdued nature works well here. I think a sparkling green tea would be good here if you can’t get tamarind.
