Twenty-four hours. That is the first thing you need to wrap your head around if you want to recreate the Dishoom black dal recipe at home. It’s not a quick weeknight side dish. It’s a commitment. When you walk into any Dishoom location—whether it’s the sprawling Shoreditch spot or the busy King’s Cross site—the smell of slow-simmered urad dal is the literal soul of the building. They call it House Black Daal, and honestly, it’s ruined most other lentils for me.
Most people think the secret is just butter. Sure, there’s a lot of it. But the real magic is time and the specific way those tiny black lentils break down until they’re basically velvet. You’ve probably seen "copycat" versions online that take forty-five minutes in an Instant Pot. Forget them. If you want that deep, smokey, dark-as-night texture that defines the London restaurant scene's most famous dish, you have to play the long game.
The Science of the 24-Hour Dishoom Black Dal Recipe
The foundation of the dishoom black dal recipe is the urad dal. These are whole black lentils, not the split ones. They’re tough. They’re stubborn. To get them to give up their starch and turn creamy without becoming a grainy mush, you need patience. Dishoom’s executive chef, Naved Nasir, has been quite open about the fact that their kitchen simmers this dal for over 20 hours. In a home kitchen, we can cheat a little with a slow cooker or a very low stovetop flame, but you can’t bypass the soak.
Soak your lentils for at least 12 hours. Overnight is better. Use plenty of water because they will drink it up like they’ve been wandering the Thar Desert. When you drain them, you’ll notice the water is dark, almost murky. That’s normal. Some people scrub the lentils between their palms to get them extra clean, which helps with the final color.
The first cook is just water and lentils. No salt yet. Adding salt too early toughens the skins of the pulses, which is the last thing you want when the goal is a texture that mimics melted chocolate. You boil them until they literally start to burst. We’re talking about a stage where if you press a lentil between your thumb and forefinger, it offers zero resistance. It should just vanish into a paste. This usually takes two to three hours on a standard hob, or longer if your lentils have been sitting in the pantry for three years (pro tip: buy fresh spices and pulses; it actually matters).
Why Most Home Cooks Fail at the Tempering
Once the lentils are soft, you move into the flavoring stage, which involves the tadka or tempering. This is where the dishoom black dal recipe separates the enthusiasts from the experts. You need ginger-garlic paste, tomato puree, and a terrifying amount of butter.
I’m serious about the butter. If you’re trying to make this a "healthy" low-fat dish, just stop now. Make a yellow tadka dal instead. The House Black Daal is an indulgence. You’re looking at around 100g of butter for a standard family-sized portion, plus a generous glug of heavy cream at the very end.

The spices are actually quite minimal. This isn't a complex masala dish. You’ve got Kashmiri chili powder—which gives that deep red hue without blowing your head off with heat—and maybe a touch of garam masala. Some folks swear by a pinch of dried fenugreek leaves (kasuri methi) crushed between the palms at the end. It adds that savory, slightly bitter note that balances out the richness of the dairy.
The Secret Ingredient is Actually Oxygen
Something people rarely talk about is the "mash." While the dal is simmering with the spices and butter, you need to use the back of your wooden spoon to occasionally smash some of the lentils against the side of the pot. This releases the internal starches. It thickens the liquid. It creates that "emulsion" effect where the fat from the butter and the starch from the dal become one inseparable, creamy entity.
If you see a layer of oil or butter floating on top of your dal, you haven't cooked it long enough or stirred it enough. It should be totally integrated. In the restaurant, they have huge vats that are constantly being stirred. At home, you’re the engine. Give it a stir every fifteen minutes. Watch the color change from a dusty grey-brown to a deep, dark, glossy mahogany.
Equipment: Slow Cooker vs. Stovetop
Honestly? Use a slow cooker if you have one. It handles the "low and slow" requirement of the dishoom black dal recipe much better than most temperamental gas stoves. You can let the lentils cook on low overnight, then add your tempering in the morning and let it keep ticking over until dinner time.
If you’re sticking to the stovetop, you need a heavy-bottomed pot. A Dutch oven is perfect. If you use a thin stainless steel pot, the lentils at the bottom will burn and catch. Once that burnt flavor gets into the dal, the whole batch is ruined. There’s no coming back from that. You’ll just have smoky-tasting disappointment.
Troubleshooting Your Texture
Sometimes, despite your best efforts, the dal stays a bit watery. This usually happens if you didn't cook the lentils long enough in the first stage. If you find yourself in this spot, don't just keep boiling it down until it’s dry. Take a cup of the lentils out, blitz them in a blender until smooth, and stir them back in. It’s a bit of a cheat, but it saves the texture.
On the flip side, if it gets too thick—like a paste—add a splash of boiling water. Never add cold water to a simmering dal. It shocks the fats and messes with the silkiness. Always use water from a kettle that’s just off the boil.
Real Expertise: The Finishing Touches
Before you serve, taste it. Then taste it again. It usually needs more salt than you think because the fats in the butter and cream mask the seasoning.
Dishoom serves their dal with a tiny swirl of cream on top and maybe some ginger matchsticks. The ginger provides a sharp, fresh contrast to the heavy, earthy flavors of the lentils. If you’re feeling particularly fancy, a side of garlic naan is non-negotiable. You need something to scoop it up. Using a spoon feels like a missed opportunity.
Essential Next Steps for the Perfect Batch
- Source authentic urad dal: Look for "Urad Dal Whole" in an Indian grocery store. If the bag says "split" or "chilka," put it back. You need the whole bean with the skin on.
- The 2:1 Butter Rule: For every two cups of dry lentils, you're going to need at least half a cup of salted butter. Don't skimp.
- The Overnight Rest: Like a good chili or beef stew, this dal actually tastes better the next day. The flavors settle. The spices penetrate the heart of the lentil. If you can, make it on Sunday to eat on Monday.
- Kashmiri Chili is Key: Don't substitute this with standard cayenne pepper. Cayenne is way too hot and lacks the smoky, fruity undertone and vibrant red color that makes the Dishoom version look so iconic.
- Manage Your Heat: If you see bubbles breaking the surface violently, it’s too hot. It should be a lazy, occasional "bloop."
Once you’ve mastered the patience required for the dishoom black dal recipe, you’ll realize that most restaurant cooking isn't about secret ingredients. It’s about the willingness to do the boring stuff—like waiting twenty hours—that most people won't do. That’s why it costs what it costs at the restaurant, and why it feels like such a victory when you pull it off in your own kitchen. Keep the heat low, keep the butter handy, and don't rush the process. High-quality black dal is a marathon, not a sprint.
