Prepare the Base: Take 2 cups of leftover dosa batter in a wide mixing bowl. If the batter is straight from the fridge, let it sit for 5-10 minutes to reach room temperature for better fluffiness.
Add the Freshness: Add the grated carrot, grated cucumber, chopped onions, chillies, and curry leaves directly into the batter. This "No-Tadka" method keeps the vegetables crunchy and nutrient-rich.
Check Consistency: Stir the mixture well. If the cucumber has released a lot of moisture and the batter looks runny, mix in 1 tablespoon of rice flour. The batter should be thick enough to drop slowly from a spoon. Add salt only if needed, as leftover batter usually contains salt.
Heat the Pan: Place the Kuzhi Paniyaram pan (Appe pan) on medium heat. Add 2-3 drops of oil into each cavity. Wait until the oil is hot—you should see a slight shimmer.
Pour the Batter: Fill each cavity about 3/4 full. Do not overfill, as the paniyaram needs space to rise and expand.
The First Side: Cover the pan with a lid and cook on medium-low flame for 3–4 minutes. Covering helps steam-cook the raw vegetables inside while the bottom turns golden brown.
The Flip: Use a wooden skewer or a small spoon to gently flip each paniyaram. Cook the other side for 2 minutes without the lid until it is golden and crispy.
Serve: Remove from the pan and serve hot for the best texture
