Roll a banana half in raw sugar. If you are using the super-sweet baby bananas, you can probably skip this step.
Wrap prepared banana half in a lumpia wrapper. You can do this "burrito-style,' or leave the ends open.
Pan-frying
Pour a scant ¼-inch of oil into a medium skillet and heat over medium heat until it reaches about 350°F | 176°C. A drop of water should immediately sizzle when dropped in the pan.
Carefully lay wrapped banana halves seam down in the pan. Do not crowd.Fry on one side until golden, and then flip and repeat on the other side.
Drain on paper towels.
Air-frying
Preheat air-fryer to it to 400°F | 205°C for 5 minutes.
Lightly brush each roll all over with oil.Immediately place oil-brushed rolls into the basket, allowing for space around each one. Do not crowd.
Air-fry for 5 minutes, until golden brown and crispy.
Serving Suggestions
Serve immediately, alone or with caramel for dipping. (They are also good hours later - they just aren't as crispy.)
Notes
Use sweet baby bananas if you can find them, but regular bananas will work just fine.
