Coconut rum does the most structural work in this drink by introducing ethanol, which lowers the freezing point of the surrounding liquid and alters surface tension. Understanding how density and temperature interact dictates the final mouthfeel of the beverage.
Temperature control remains the primary mechanism for maintaining proper viscosity in mixed drinks. Proper agitation introduces microscopic air bubbles that soften the alcoholic burn on the palate.
