Malta Goya - "Malta" is of Caribbean origin. Non-alcoholic, brewed with barley and hops. Malta Goya is primarily a Puerto Rican brand of Malta.

Drinking it quickly would probably be a bad idea, as it's a little "heavy."
Surullitos are fried corn sticks that are wildly popular appetizer food in Puerto Rico. In this authentic surullitos recipe, a quick, homemade cornmeal dough is mixed with cheese, rolled into cigar shapes and fried.
