Banana cue is basically saba (cooking bananas) rolled in sugar and deep fried in hot oil. The heat will caramelize the sugar while on the banana making the outside crisp to the bite but soft inside. The bananas are then strung together (usually two or three) with a bamboo skewer.
While you can certainly make bananacue, it is really a street food and best purchased from your suki na maglalako (your favorite vendor). He/she has been doing this for awhile and theirs would be so much superior than your own. Really.

One last look. Oh, be sure not to bite on the banana when it just got made as it would be very hot inside!
