Dhal Wadi: How to Make and Dry Lentil Dumplings at Home

Dhal wadi are small, seasoned lentil dumplings that are dried until firm, then fried or simmered in a curry or stew. Across South Asia, recipes and names vary by region and household; this version uses split mung dal with ginger and spices, and makes a batch to cook with later.

Plan ahead: the lentils need a four-hour soak and the shaped wadis need a long, low drying period. A food dehydrator gives the most predictable result; a low oven works too. A blender or grinder, baking trays, and enough space to dry the dumplings without crowding them are useful.

What You’ll Need

1 cup (200 g) split yellow mung dal, also called split mung beans
¼ cup (50 g) split urad dal, for a slightly firmer, more savory texture; replace it with the same amount of mung dal if unavailable
½ teaspoon cumin seeds
½ teaspoon coarsely ground black pepper
¼ teaspoon asafoetida (hing), optional; if you cannot find it, omit it or use a small pinch of garlic powder, which gives a different flavor
1 teaspoon finely grated fresh ginger
1 small green chile, finely chopped, optional
¾ teaspoon fine salt
2–4 tablespoons (30–60 ml) water, as needed for grinding
Neutral oil, a few drops, for greasing the spoon or piping bag if needed
Equipment: a blender or spice-and-grain grinder, a spoon or piping bag, parchment-lined trays, and a food dehydrator or oven

Step-by-Step

Sort and rinse the lentils. Pick through both dals for any small stones or damaged pieces. Rinse them in a bowl or fine sieve, changing the water until it looks mostly clear. Put the lentils in a large bowl and cover with several inches of cool water; they expand as they soak.
Soak for four hours. Leave the bowl at room temperature for four hours, then drain the lentils very thoroughly. A longer soak can make the paste too wet and may make the wadis slower to dry. If your kitchen is very warm, soak them in the refrigerator and allow extra time for them to soften.
Grind to a thick paste. Add the drained lentils to a blender or grinder with the ginger, chile, salt, cumin, pepper, and asafoetida. Grind in short bursts, scraping down the sides as needed. Add water a tablespoon (15 ml) at a time only when the blades cannot move the mixture. Stop when the paste is thick and mostly smooth, with a little texture; it should hold a mound on a spoon rather than pour.
Beat the paste briefly. Transfer it to a bowl and beat vigorously with a spoon for two to three minutes. This incorporates a little air and helps the mixture hold its shape. Lift a spoonful: it should fall slowly, not run like pancake batter. If it is loose, stir in a tablespoon (about 8 g) of additional ground lentils, if available, and let it stand for ten minutes to thicken.
Prepare the drying trays. Line trays with parchment or use the nonstick sheets supplied with your dehydrator. Leave space between trays so air can circulate. Make sure the equipment and trays are clean and fully dry. Avoid placing the batter on bare fabric, which can stick to the dumplings and is harder to clean.
Shape small, even portions. Use a teaspoon to drop rounded mounds about ½ inch (1.25 cm) across onto the lined trays, or pipe similar-sized dots from a piping bag. Keep each wadi small and close to the same size so they dry evenly. Leave about ½ inch (1.25 cm) between them. The batch should make roughly 36 small pieces.
Dry in a dehydrator. Arrange the trays with room for airflow and set the dehydrator to 135°F (57°C). Dry for about ten hours, rotating trays if your machine dries unevenly. The exact time depends on the size of the wadis and your appliance, so check the texture rather than relying only on the clock. The pieces should be hard and dry all the way through, not soft or cool and damp in the center.
Use a low oven if needed. If you do not have a dehydrator, set the oven to its lowest available temperature, ideally around 170°F (77°C). Put the trays on the center racks and keep air moving; if your oven has no fan, briefly open the door every so often to let moisture escape, taking care around the hot oven. Check the wadis after six hours and continue until completely dry, which may take ten hours or longer. Oven temperatures vary, so avoid turning the heat up to rush the process.
Cool, check, and pack. Let the wadis cool completely on the trays. Break one open: it should be dry and firm inside, without a moist, doughy center. If it is not, return the batch to the dehydrator or oven. Once fully dry and cool, transfer the pieces to a clean airtight container and refrigerate or freeze them. Label the container with the date.
Cook the wadis before serving. These are dried lentil pieces, not ready-to-eat snacks. For a curry, brown a few in a little oil until lightly golden, then simmer them in a thin sauce or gravy until tender in the center. You can also crumble them into a vegetable stew. Add them early enough to absorb liquid, and taste the sauce before adding extra salt because the wadis are already seasoned.

For the most even results, use a small spoonful of paste for each piece and keep the tray size consistent. If you are making a larger batch, dry one tray first as a timing guide before shaping more. The stated ten-hour drying time is an estimate for small pieces in a dehydrator; larger portions, humid conditions, and less powerful equipment can all extend it.

Common Mistakes

Adding too much water during grinding: A thin paste spreads into flat puddles and takes longer to dry. Start with no added water, then add it in small amounts only if the grinder needs help. If the paste is already loose, mix in a little more ground lentil and wait for it to absorb moisture before shaping.

Making the wadis too large: A large mound can look dry on the outside while remaining damp in the middle. Keep them around ½ inch (1.25 cm) wide and similar in thickness. If some are bigger than others, separate them on the tray so you can remove the small ones when they are ready.

Overloading or stacking trays: Crowded pieces and blocked vents slow drying and can leave sticky spots. Leave room around every wadi and follow your dehydrator’s guidance for tray spacing. In an oven, do not cover the pieces or place trays directly against the oven walls.

Stopping when the outside feels dry: A dry shell does not guarantee the center is ready. Cool and break open one of the thickest pieces. If its center bends, smears, or feels damp, keep drying the whole batch and check again later.

Storing the wadis while warm or damp: Trapped warmth and moisture can lead to condensation in the container. Cool them fully, confirm that the centers are dry, and refrigerate or freeze them in a clean, airtight container. Do not leave a questionable batch at room temperature for storage.

Tips

Use split lentils rather than whole lentils for a quicker soak and easier grinding. If using a different split dal, expect a modest change in color, flavor, and firmness.
Keep the seasoning restrained if you plan to add the wadis to a strongly seasoned curry. Cumin, pepper, ginger, and chile are adjustable; start with less chile if you want a milder batch.
Crush the cumin lightly before adding it if you want its aroma distributed through the paste. Whole seeds also work, but create small pockets of spice in the finished pieces.
Use a piping bag for neat, evenly sized shapes. A teaspoon works just as well; dip it in a little oil if the mixture sticks, but avoid adding oil directly to the paste.
For cooking later, brown only the number of wadis you need. Add them to a sauce with enough liquid to soften them, and simmer gently until the middle is tender. Very hard wadis may need a longer simmer or a brief soak in warm water first.
Write the drying date on the storage container and keep the batch refrigerated or frozen. If the wadis develop an unusual smell, visible mold, or signs of moisture, discard them rather than tasting them.

Troubleshooting

The grinder stalls or the paste stays coarse: Stop the machine and scrape down the sides. Add water one tablespoon (15 ml) at a time, not a large splash, and grind in short pulses. A coarse paste can still work, but very large lentil pieces may make the texture uneven; give the drained lentils another short soak if they remained hard.

The mixture spreads after shaping: It is likely too wet or was not beaten enough. Scrape the paste back into a bowl, beat it for another minute, and let it rest for ten minutes. If it still flows, add a little finely ground dal. Shape a test piece and check that it keeps its mound before filling the trays.

The wadis are sticky after the suggested drying time: Continue drying rather than raising the heat sharply. Check the temperature setting and make sure vents are clear. Turn or rotate trays if one area is drying more slowly, and test one of the thickest pieces again after an hour.

The outside is browning in the oven: The oven is too hot for gentle drying. Lower the temperature to the minimum setting, move the tray away from a hot element, and check more frequently. If the oven cannot stay low, use a dehydrator or dry in shorter monitored periods rather than scorching the pieces.

The wadis crumble when moved: They may be fully dry and brittle, which is normal, or they may have been shaped too loosely. Let them cool before lifting; warm pieces are more fragile. For the next batch, beat the paste well and use a slightly thicker mixture so the mounds hold together.

The cooked wadis stay tough in curry: They may be unusually thick, very old, or not given enough simmering time. Add a splash of water or broth, cover the pan, and cook gently until tender. Next time, make smaller pieces or soak the dried wadis briefly before adding them to a thick sauce.

Frequently Asked Questions

Can I make dhal wadi without urad dal?
Yes. Replace the ¼ cup (50 g) of urad dal with the same amount of split mung dal. The flavor will be a little milder and the texture may be slightly less firm, but the method stays the same.

Can I dry dhal wadi in the sun?
Sun drying is used traditionally in some places, but it depends on reliably hot, dry weather, good airflow, and protection from dust and insects. A dehydrator or low oven is more controlled. Do not leave the batter exposed outdoors in humid, rainy, or otherwise unreliable conditions.

How can I tell if the wadis are completely dry?
Cool one piece, then break it open. It should be firm and dry through the center, with no soft, sticky, or damp patch. If you are uncertain, continue drying and check again; judging by the outside alone is not enough.

How should I store homemade dhal wadi?
Cool them completely, then refrigerate in a clean airtight container or freeze them. Keep the container dry and take out only what you plan to cook. Discard the batch if it becomes damp, smells unusual, or shows visible mold.

Do I need to fry dhal wadi before adding it to curry?
No, but lightly browning the pieces in oil adds a toasted flavor and helps them keep their shape. If you prefer not to fry them, add them directly to a simmering, fairly thin sauce and cook until tender. They absorb liquid as they soften.

Can I change the spices?
Yes. Keep the lentil-to-water balance and drying method the same, but adjust the chile, cumin, and pepper to suit the dish you plan to make. Asafoetida is optional; leaving it out changes the aroma but does not prevent the wadis from drying.
