Ultra-Rich Version: Reduce the milk beverage to ¼ to ¾ cup, and blend in ¼ cup of thick, spoonable coconut cream with the other ingredients. I really liked it this way!
Coquito Ice Cream Option: Make the Ultra-Rich Version above, and reduce the rum to ½ cup to 1 cup. A full cup of rum will make it very creamy, but it will taste very spiked (Tony liked it that way). Using just ½ cup will make it less rum forward.
