I am puertorican and have never heard of our traditional coquito being made with Malibu rum. It is traditionally made with Bacardi rum, which is a puerto rican rum.
This recipe came out great. I made a few changes, Bacardi white rum instead of malibu and egg nog instead of egg substitute. This was my first time making an alcoholic beverage and it was wonderful for the holiday season.
Excellent recipe! I use Bacardi instead of Malibu though. Really good stuff.
