Grease a dosa pan with 1/2 tbsp. oil and spread the batter into a slightly thicker consistency. Poke 4 or 5 holes in the adai using fingers or wooden spatula (see recipe photo). Pour oil around the edges and inside each hole. Wait for about 2 to 3 mins and once it is browned at the bottom, flip and cook on the other side for 2 to 3 mins. Flip few times to get consistent crispy browning on both sides.
