Mix flour, salt, chilli powder, cumin and baking powder in a bowl. Stir in approx. 275 ml of cold water with a whisk until a smooth, thick dough is formed. Peel onions and cut into slices. Clean and wash the cauliflower and cut into florets. Peel and wash potatoes and cut them into thin slices. Peel bananas and cut into pieces. Heat the oil in a high pot to approx. 180 °C.
In the meantime, wash coriander, dab dry and chop, except for a few leaves for garnishing. Stir into the mango chutney. Use a fork to pull the vegetable pieces through the dough one by one, let them drip off a little and fry them in portions in hot oil for a few minutes until golden brown and crispy. Take them out and let them drip off on kitchen paper. Arrange the vegetables on a plate. Garnish with coriander, salad and lime. Add mango chutney extra
