Crispy Rava Dosai from Leftover Idli & Dosa Batter
7/20/2026
A delicious way to transform leftover idli or dosa batter into something everyone looks forward to.
"Some of Amma's best recipes were never planned. They were born from simple kitchen wisdom—never waste good food."
Whenever our idli or dosa batter was down to just a few serving spoons—not enough to feed the whole family—Amma never let it go to waste.
Instead, she'd smile and say, "Let's make rava dosai."
With a handful of fine rava, rice flour, a few pantry staples, and plenty of water, she transformed that little bit of batter into golden, lace-like dosais that disappeared as quickly as they came off the hot cast-iron tava.
Today, I still make them exactly the way she taught me. Every crispy dosa reminds me that some of the best family recipes aren't carefully planned—they're born from experience, resourcefulness, and love.

🛒 Ingredients
- 1–2 cups leftover idli or dosa batter
- ½ cup fine rava (sooji)
- ¼ cup rice flour
- ¼ cup maida (all-purpose flour)
- 1 medium onion, finely chopped (optional if you want to make Onion Rava Dosa)
- 2 green chilies, finely chopped
- 1 teaspoon grated /finely chopped ginger

- Fresh coriander leaves (optional)
- 1 teaspoon mustard seeds
- ½ teaspoon cumin seeds
- Salt, if needed
- Water, as required, to make a thin, flowing batter
- Oil for Thadka and cooking
👩🍳 Method
Step 1 – Prepare the Batter
In a large bowl, combine the leftover batter with the fine rava, rice flour, and maida.
Add the chopped onions, green chilies, ginger, curry leaves, coriander, and salt if required (remember the left over batter should have some salt).
In a small pan, heat 1 teaspoon oil. Add 1 teaspoon mustard seeds and ½ teaspoon cumin seeds. Once the mustard seeds splutter, pour this tempering (thadka) into the batter and mix well.
🤲 Amma's Secret – Mix the Batter with Your Hand
One lesson Amma always insisted on was never rush this step.
After adding all the ingredients and the tempering, gently mix the batter with your hand, not a spoon or whisk.
She believed your hand helps break up any tiny lumps of rava, evenly distributes the ingredients, and gives you the perfect feel for the batter's consistency. As you mix, you'll know if it needs a little more water and if everything is mixed evenly.
It may sound old-fashioned, but some traditions exist for a reason. Even today, I still mix the batter with my hand—just the way Amma taught me—and somehow, the dosas always turn out a little crispier and a little better.
"Sometimes the best kitchen tool isn't found in a drawer—it's the one you were born with." 🍃
Gradually add water until the batter becomes very thin and pourable—much thinner than regular dosa batter.
Let it rest for at least 15–20 minutes. I usually prepare the batter right after lunch for making dosa at dinner time, this helps to get tastier dosas.
Step 2 – Heat the Tava
Heat a well-seasoned cast-iron dosa tava until evenly hot.
Lightly grease it with a few drops of oil to avoid the batter from sticking to the tava.
Step 3 – Pour the Batter
Give the batter a good stir before every dosa, as the rava settles at the bottom.
Instead of spreading the batter using a normal serving spoon like we do for normal dosa, take the batter in a tumbler or dabara (larger cup) and pour it in a circular motion from the outside toward the center.
Don't try to fill all the gaps.
Those tiny holes are what give Rava Dosai its beautiful lace-like texture and signature crispness.
Spread some oil around the edges and a few drizzles in the holes for those edges to get crispy too.
Cook until the bottom becomes deep golden and crisp.
Flip it to cook both sides. Remove when its crispy enough before it burns and serve hot.

💚 Amma's Kitchen Tip
If you have your mom's or grandmother's well-seasoned cast-iron dosa tava, treasure it.
Years of seasoning create the naturally crisp texture that makes homemade Rava Dosai so special. Mine is one of my favorite kitchen heirlooms, and every dosa I make on it carries a little piece of family history.
Slightly fermented leftover batter gives this rava dosai its signature flavor and beautiful golden color. That's why this recipe tastes even better than making it from fresh batter.
Also, remember to stir the batter before making every dosa. Since the rava settles quickly, stirring ensures every dosa comes out perfectly crisp.
There is a delicate balance to adding the right quantity of water to the batter – so it does not run off the tava when we pour it. Once you try this a few times, you can get a feel for the batter consistency.
"The best recipes aren't just written down—they're lovingly passed from one kitchen to another."
Thank you, Amma, for teaching us that the simplest ingredients, treated with care and love, can become the meals we remember forever.
I hope this recipe brings the same warmth, comfort, and joy to your family that it has always brought to ours.
Happy Cooking! ❤️
