Make a medium thick batter with cornflour, plain flour, salt and water. Dip the whole baby corn in this batter and fry till it turns golden brown.
Cut the fried baby corn into medium size cubes. Keep it aside.
Heat oil in a pan and add chopped onion. When it turns golden brown, add ginger and garlic. Cook for 2-3 mins. Add crushed pepper and crushed red chilli. Stir well. After a min or two, add soya sauce and tomato ketchup. Stir well. Add salt and 2-3 tbsp hot water just to bring everything together. Add fried baby corns and combine everything. Add the chopped spring onions. Stir and remove from gas. Serve hot.
Notes
Be careful while adding salt, since we are also using soya sauce. The recipe is a bit spicy, so you can adjust the qty of pepper and red chilli to suit your taste.
