Deseed and slit capsicum in thick vertical strips. Slice baby corn in vertical halves.
Peel and stil the banana vertically in quarters. Keep aside.
Mix the flours, vinegar sauces, ginger, garlic, chilli and salt and make a batter.
The batter should not be too thick, it should coat the vegetables slices thinly.
Heat oil in a frying pan, dip the vegetables, in the batter, piece by piece.
Gently put into the hot oil. Allow to become crisp on medium heat.
Drain and place on a kitchen paper to absorb extra oil.
Serve hot with tomato ketchup or red chilli garlic sauce.
