Preheat oven to 350°F (176°C).

Grease a 20 cm cake pan.

Cream butter and sugar together in a large bowl until light and fluffy.

Add honey, mashed banana, orange rind, and lemon juice.

Beat well to combine.

Add eggs one at a time, beating well after each addition.

In a separate bowl, sift together flour and salt.

Gradually fold the sifted flour mixture into the wet ingredients, alternating with orange juice.

Continue folding until just combined; do not overmix.

Pour batter into the prepared cake pan.

Bake for 1 hour, or until a wooden skewer inserted into the center comes out clean.

Let cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
