Black Lentils UK vs Urad Dal: Which Should UK Cooks Buy for the Best Results?

They look almost identical in the bag. Both are small, dark, glossy, and broadly the same colour. Sit them side by side at a UK Asian grocer or at Whole Foods and most shoppers couldn't tell them apart. But black lentils and urad dal are two genuinely different ingredients, from two different plant families, that behave completely differently in the pot.

If you cook both Italian and Indian food, you actually want both. If you only cook one cuisine, picking the right one matters more than the price tag suggests.

What They Actually Are

Black lentils (Lens culinaris) are members of the lentil family. Round, slightly flattened, often called “beluga” in commercial naming. They range from large industrial macrosperma types down to small heritage Mediterranean varieties like the Villalba lentil from central Sicily.

Urad dal (Vigna mungo) is whole or split black gram — a different legume species entirely, native to the Indian subcontinent. It's a pulse, but botanically it's closer to mung beans than to lentils. In Indian cooking it appears whole (kala urad) or split with the skin removed (urad dal dhuli, which is white).

How They Cook

• Black lentils: rinse and cook. 25–30 minutes. No soak required. Hold their shape.
• Whole urad dal: 6–8 hour soak strongly recommended. 60–90 minute simmer. Releases starch and becomes creamy.

The behaviour in the pot is the giveaway. Black lentils stay distinct, intact, with bite. Whole urad dal releases a thick, almost buttery starch that gives Indian dishes like dal makhani their signature silken texture.

Flavour Profile

Black lentils taste earthy and mineral, with a clean buttery finish. They're a quiet flavour that lets olive oil, herbs, and finishing ingredients do the talking. Excellent supporting actor.

Urad dal tastes richer, more savoury, slightly nutty, with a pronounced creamy mouthfeel from the starch. It carries Indian spice extremely well — it's the backbone of dal makhani, idli batter, dosa batter, and several regional South Indian dishes.

Best Cuisines for Each

Black lentils excel in:

• Mediterranean salads
• Italian pasta e lenticchie
• Sicilian lentil soup
• Side dishes for roast meat
• Modern bowls and grain bowls
• Western lentil preparations where texture matters

Urad dal excels in:

• Dal makhani (the classic creamy Punjabi black lentil dish, which is actually urad)
• South Indian idli and dosa fermented batters
• Vada (deep-fried savoury fritters)
• Spiced dal preparations needing a silken finish

The Most Common Mistake

Substituting urad dal for black lentils in a recipe, or vice versa, produces a disappointing result. UK home cooks attempting dal makhani with black lentils end up with a thin, lean dish lacking the trademark creaminess. UK home cooks attempting pasta e lenticchie with urad dal end up with a mushy starch-bomb that doesn't work with pasta.

Use the right pulse for the right cuisine.

The UK Availability Picture

Urad dal is widely available at any UK Asian grocer or online specialist, in both whole and split forms, at low prices. Commodity black lentils are equally common at UK supermarkets. The harder thing to find in the UK is a heritage Mediterranean black lentil variety — the smaller, denser, more flavourful Villalba type from central Sicily, which is the lentil that genuinely elevates Italian lentil dishes from acceptable to memorable.

The Verdict

If you cook Indian food regularly, keep urad dal in your pantry. There is no substitute for it in dal makhani, idli batter, or vada. If you cook Mediterranean and modern European food, keep heritage black lentils in your pantry. The difference between a commodity supermarket lentil and a heritage Sicilian one is significantly larger than most people realise — and it's the foundation of every great lentil dish in that culinary tradition.

FAQ: Is dal makhani made with black lentils?

Confusingly, no — despite the colour. The “black lentils” in dal makhani are actually whole urad (kala urad), a different legume species. This is one of the most common naming confusions in UK Indian cookbooks.

FAQ: Can I use urad dal instead of black lentils in Italian lentil soup?

Not recommended. Urad dal becomes creamy and starchy when cooked — the opposite of what an Italian lentil soup wants, where the lentils should remain distinct and slightly firm.

FAQ: Are black lentils and beluga lentils the same thing?

“Beluga” is a commercial marketing name for small dark lentils. It covers multiple varieties, from large macrosperma commodity stock down to small heritage varieties like the Villalba from central Sicily. They are all Lens culinaris — but they differ significantly in size, density, and flavour.

FAQ: Do urad dal and black lentils have similar nutrition?

Both are high in plant protein (~24–25g per 100g dry) and fibre, with similar mineral profiles. Nutritionally they're broadly equivalent. The difference is culinary, not nutritional.

FAQ: Which is more expensive in the UK?

Commodity versions of both are similarly priced. Premium heritage black lentils (Villalba and similar) command a meaningful premium because they're far rarer; there's no equivalent heritage tier for urad dal in UK retail.
