Rinse the urad dal under cold water until the water runs clear, then drain. Put it in a bowl with 700 ml water and soak for 4 hours or overnight until the dal swells and splits easily when pressed.
Drain the soaked dal very well and transfer to a blender or wet grinder. Add the green chillies, ginger and 2 tbsp fresh water. Grind to a thick, smooth paste, scraping down the sides, adding only 1 tsp water at a time if needed. The batter should be fluffy and hold its shape, not runny.
Transfer the batter to a bowl. Add the curry leaves, asafoetida, salt and optional onion and black pepper. Beat the batter with your hand or a spoon for 2 minutes to aerate it; it should lighten in colour and feel airy. If it looks wet, sprinkle in the rice flour and mix.
Heat the vegetable oil in a deep, heavy pan over medium heat until it reaches 170°C. To test, drop a small piece of batter into the oil; it should rise to the surface and sizzle steadily without browning instantly.
Wet your palms with water. Take a lemon-sized ball of batter, flatten it into a 6 cm disc, and poke a hole in the centre with your thumb. Slide it gently into the hot oil. Repeat with 3 to 4 vadas per batch, keeping your hands wet between shaping.
Fry the vadas for 2 to 3 minutes per side, turning with a slotted spoon, until they are deep golden brown and crisp all over. Drain on a wire rack or kitchen paper. Serve hot with coconut chutney and sambar.

Kitchen notes
Kitchen notes
- The most common mistake is a watery batter: drain the dal thoroughly after soaking and grind with minimal water, or the vadas will drink oil and turn soft.
- Beat the ground batter well before frying. This incorporates air and is what makes the inside fluffy rather than dense.
- Keep the oil at a steady 170°C. If it is too hot the vadas brown outside while staying raw inside; if too cool they absorb oil and become greasy.
- Shape the vadas with wet hands and slide them in gently; a dry hand makes cracks and a rough surface that breaks in the oil.
Substitutions
- urad dal→split urad dal with skin (chilka urad dal) for a slightly earthier vada, though the colour will be darker
- rice flour→1 tbsp semolina or cornstarch to tighten a wet batter
- asafoetida→1 small crushed garlic clove for a similar savoury depth
- vegetable oil→any neutral high-smoke-point oil such as sunflower or rice bran oil
Storage & reheating
Medu vada is best eaten within 30 minutes of frying. To store, cool completely and keep in an airtight container in the fridge for up to 2 days; the texture softens. Reheat in a 180°C oven or air fryer for 6 to 8 minutes until crisp again, or shallow-fry in a little oil for 1 minute per side. Do not freeze the fried vadas; the batter itself can be frozen for up to 1 month in a sealed container, thawed overnight in the fridge and beaten again before shaping.
FAQ
The questions we get asked most
Why did my medu vada break apart in the oil?
The batter was too wet or not beaten enough. Drain the soaked dal thoroughly, grind with as little water as possible, and beat the batter for 2 minutes until it is light and airy. If it still feels loose, mix in 1 tbsp rice flour before shaping.
Why are my vadas oily and soft instead of crisp?
The oil was not hot enough, so the vadas absorbed oil before the crust set. Heat the oil to 170°C and test with a small piece of batter; it should rise and sizzle steadily. Fry in small batches so the temperature does not drop.
Can I make the batter ahead of time?
Yes, grind the batter and keep it covered in the fridge for up to 24 hours. Bring it to room temperature, then beat it again for a minute before shaping, as cold batter can be stiff and may crack in the oil.
Can I use canned or pre-soaked urad dal?
No, canned urad dal is cooked and will not grind into a fluffy, sticky batter. You must soak dried split urad dal for at least 4 hours; overnight soaking gives the best texture.
How do I know when the medu vada is cooked through?
The vada turns deep golden brown on both sides and feels firm and light when lifted with a slotted spoon. If you break one open, the inside should be pale, fluffy and cooked, not doughy or wet.
Can I add onions or other vegetables to the batter?
Yes, finely chopped onion, grated carrot, chopped coriander or crushed black pepper can be folded in after grinding. Add them just before frying and do not let the batter sit too long, as the vegetables release water and loosen it.
Why is my batter not fluffy even after grinding?
The dal was not soaked long enough or too much water was added during grinding. Soak until a piece breaks easily, drain completely, and grind in small batches with only 1 tsp water at a time. Beating the batter afterwards also adds the air needed for fluffiness.
