Preheat oven to 200°C.
Slice the bottom most portion of the potato so that it becomes flat and stands without rolling.
Then with a sharp knife, cut the potato into thin slices stopping at 3/4th so that all the slices are intact.
Now slice garlic pods into thin slices and press them into the potato cuts.
Mix all the spice powders with oil and salt.
Now drizzle this spice oil on the potatoes and make sure that they coat the inside of the slices.
Bake the potatoes for 30-45 minutes or until crisp in oven.
Serve hot along with rice and gravy..
