Zubereitung

1. 1

   Wash the bananas and cut them lengthways without peeling them, without cutting through the skin underneath. The skin then stays a closed shape from which nothing runs out.

2. 2

   Drizzle the cut with the lemon juice so that the flesh stays pale, and press the opening apart a little with your fingers.

3. 3

   Mix the sugar with the cinnamon and fill it into the opening, scatter the chopped hazelnuts over it and set a small piece of the butter or margarine on each banana.

4. 4

   Preheat the air fryer to 180 °C.

5. 5

   Lay the bananas with the opening facing up in a single layer in the basket, spaced apart and not stacked; cook a larger quantity in two batches. Cook at 180 °C.

6. 6

   Carry on cooking the bananas at 180 °C without turning them until the skin is black and the flesh is completely soft. Do not turn them, as the filling would otherwise run out of the cut.
