“Pani Walalu/ Undu Walalu” is a Sri Lankan traditional new year sweet that made out of fermented split black gram paste. You only need a few ingredients for this recipe but you have to plan ahead of time since you have to soak the beans and then ferment the grounded bean paste for quite a long time.

Split black gram is also known as urad dal or Undu in south Asian countries. It’s a very popular ingredient in South India and Sri Lanka that is also used to make dishes such as Dosa, Medu vada, and Idli and so many more. So even if you’re not living in South Asia you’d still be able to find this ingredient easily at your local Indian grocery store.

Tips and Important Info

I have a few key points that need to address before I go to the recipe. Please go through the recipe and the notes below a few times before you start making these.

  1. You have to soak beans overnight for at least 8 hours. You’re going to grind the beans without any liquid added so it’s important that they are soft and plumped from soaking.
  2. The grounded paste has to ferment for at least 12 hours until you see some bubbles have appeared. If you live in a cold area ferment it for more than 12 hours. If you’re in Sri Lanka or any other hot and humid area 10 hours would probably be enough. Good fermentation of the batter is important to make the coils hollow in the middle and for the slightly tangy taste that we all love.
  3. You have to keep the syrup warm all throughout the Pani Walalu frying process. That’s what makes the hot fried Pani Walalu absorb the syrup without losing the crispiness. 
  4. Oil shouldn’t be too hot. Keep it on medium-low heat. So the piping of the batter would be easier. You’d have more time to pipe the batter into coils before it starts to bubble up and popup onto the surface of the oil. 
  5. If you add too much coconut cream by any mistake, add a little bit of rice flour to get the right consistency. But this may harden your Pani Walalu’s a little bit. So be careful when you add coconut cream/milk

For the Batter

For the Sugar syrup



  1. Soak Urad dal/Undu overnight. (or 8-10 hours)

  2. Drain water you used to soak black lentils. Grind lentils into a smooth paste. Use about a tsp of water at a time if only it’s hard to grind. Otherwise no need to add any extra water. Mix the ground urad dal with rice flour and all-purpose flour. It would become a little stiff but a smooth paste. If the mixture is very dry and hard to mix add about tbsp of water and mix well. Cover with plastic wrap. Let the batter ferments for 12 hours or so until you see it has tiny bubbles/holes in it.

    If you live in a colder climate, turn on the oven light and leave it in the oven for 12 hours. DO NOT turn the oven on.
  3. After the batter is fermented, add salt to the mixture and coconut cream one tablespoon at a time and make it into a pipable paste. Do not over-mix since you can lose the air bubbles in the batter. In case it looks flat and no air in the batter leave it for about an hour before you pipe them into hot oil. It’s important not to add too much coconut milk since it would be hard for you to get the coil shape with a runny batter.

  4. Make the sugar syrup by heating dark brown sugar, water, and salt in a saucepan. Do not overheat the syrup until it becomes bubbly. You only need to heat it through. Keep it on the stove on very low heat. (you can substitute dark brown sugar with white sugar or jaggery or even use treacle as a substitute for syrup)

  5. Heat enough oil to deep fry in a frying pan. (a flat bottom pan would be ideal). Put a bit of batter into the oil to see if it has heated enough. It should sink to the bottom first, stay for about a second, and pop onto the surface of the oil, and should puff up. If it popup immediately, the oil is too hot. Let it cool down a little bit before you pipe the batter again. Keep the piping bag closer to the surface of the oil so it's easier to get the right shape. And do not use way too much oil to deep fry. 1.5 inches deep should be enough.

  6. When the oil is heated enough pipe the batter into coils. Fry them until golden brown. When it’s golden brown immediately transfer to the warm syrup. Do not crowd the pan and soak one Pani Walalu at a time in the sugar syrup.
  7. Leave the Pani Walalu in syrup for a few seconds until it absorbs the syrup and transfer into a clean plate.
