Cook the potatoes in a large saucepan of salted, boiling water for 10-15 minutes until just tender. Remove from the heat and drain, leaving the potato to cool to one side. Carefully place the eggs in a large saucepan of boiling water and cook for 12 minutes. Drain and run under cold water for 1 minute. Heat the oil in a frying pan until hot then add all the spices apart from the tandoori curry powder. Cook over a low heat for 1 minute, then stir in the lemon juice, a little water and seasoning so that you have a thin sauce. Add the sauce to the potatoes and stir well. Peel the eggs then roll in the tandoori curry powder so that they are covered in the spice. Spoon the potato into serving bowls then cut the eggs in half and sit on top of the potato. Season and serve.
