Jamoca

Combine the Puerto Rican rum, Jamaican rum, chilled coffee, brown sugar coffee syrup, and lime juice in a blender.

Add a generous amount of crushed ice.

Blend briefly, ensuring not to exceed a few seconds for an optimal texture.

Pour the mixture, unstrained, directly into a Pilsner Glass.

Top with additional crushed ice to achieve the desired fullness.

Serve immediately with a straw for a refreshing experience.
