Masoor Dal — Cups to Grams

Masoor Dal Measurements: Dry vs. Cooked

The single most important measurement consideration with masoor dal is distinguishing between dry (raw) and cooked weight and volume. Recipes may specify either — and the difference is substantial enough to completely change the yield of a dish.

Dry masoor dal (190g/cup): The raw, uncooked lentil. This is the form in which dal is purchased, stored, and measured for recipes specifying dry lentils. The density is relatively high because the tiny split lentils pack efficiently with minimal air gaps. A 500g bag of masoor dal = approximately 2.6 cups dry.

Cooked masoor dal (245g/cup): Fully cooked, completely soft, falling-apart lentils as used in dal dishes. The cooked lentils are denser per cup than raw because they have absorbed water and lost their structural integrity — they compact into a near-uniform mass in the cup. This measurement applies when a recipe calls for pre-cooked or leftover dal.

The rehydration math: 1 cup (190g) dry masoor dal + 2.5 cups (591ml) water yields approximately 2.5 cups (490-500g) cooked dal. The 1.6x weight increase (190g to 490g of cooked dal) accounts for absorbed water.

Masoor Dal in Indian Cuisine: Dal Tadka, Mulligatawny, and More

Masoor dal is eaten daily across India in dozens of regional variations. Its fast cooking time and ability to dissolve into a smooth, thick soup make it especially suitable for everyday home cooking where long-simmered preparations are impractical.

Dal tadka (North India, universally popular): The everyday Indian household dal. Cooked masoor dal (or toor dal) is tempered with a sizzling ghee-and-spice mixture poured on top at serving. The ritual of the tarka (tempered spice oil) transforms a simple lentil soup into an aromatic, layered dish. See the FAQ above for full ratios.

Masoor dal soup (simple, weekday): 1 cup (190g) dry masoor dal + 1 can (400ml) diced tomatoes + 600ml water + 1 teaspoon turmeric + 1 teaspoon cumin + 1 teaspoon coriander + 1 teaspoon salt. Simmer 20 minutes until completely smooth. Blend if desired. Serves 4 as a light soup. Add coconut milk (200ml) for a creamier, South Indian-adjacent flavor.

Mulligatawny soup: A British-Indian hybrid soup with Indian roots (from Tamil milagu-tannir — pepper water). Modern versions commonly use masoor dal as the base: 1 cup (190g) dry masoor dal + chicken or vegetable stock (1 liter) + 1 apple (diced) + curry powder (1.5 tablespoons) + coconut milk (200ml). Simmer 20 minutes, blend smooth. The masoor dal provides body and thickening without flour or starch. Serves 4-6.

Tarka (Tadka): The Tempering Technique

Tarka is one of the fundamental techniques of Indian cooking — hot fat infused with spices by frying them briefly at high heat, then poured over a finished dish to add aromatic depth. The high-heat contact (oil at approximately 160-180 degrees C) causes the Maillard and pyrolysis reactions in the spices that release their volatile aromatic compounds far more efficiently than low-heat simmering would.

The sequence matters: hard spices (cumin seeds, mustard seeds) go in first and are fried until they crackle or pop — approximately 20-30 seconds in hot ghee or oil. Dried whole chilies go in next (20 seconds). Then powdered spices (hing/asafoetida, turmeric) for just 5-10 seconds — powdered spices burn very quickly. Finally, aromatics like minced garlic or curry leaves, which require only 30-60 seconds. The entire tarka process takes 60-90 seconds from start to pour.

For masoor dal tadka (4 servings): heat 2 tablespoons ghee until shimmering. Add 1 teaspoon cumin seeds — they should crackle immediately. Add 3-4 dried red chilies, cook 20 seconds. Add 1/2 teaspoon asafoetida (hing) and 2 cloves garlic, minced — cook 30 seconds stirring constantly. Pour the entire sizzling tarka over the pot of finished dal, cover the pot immediately for 30 seconds to trap the aromatic steam, then stir and serve.

Nutritional Profile and Storage

Masoor dal is among the most nutritionally efficient plant foods by calorie — high in protein, fiber, iron, and folate, with minimal fat and a relatively low glycemic index despite the carbohydrate content. The folate content is exceptional: 100g dry masoor dal provides approximately 480mcg folate, more than the full adult daily requirement.

Iron content (7.5mg per 100g dry) is high for a plant food, though plant-source iron (non-heme iron) has lower bioavailability than animal iron. Vitamin C significantly improves non-heme iron absorption — squeezing lemon juice over dal tadka is both traditional and nutritionally beneficial. Cooking with a cast-iron pot increases the iron content of the finished dal by 2-3mg per cup.

Storage: dry masoor dal keeps for 2-3 years in a sealed container at room temperature — one of the most shelf-stable pantry staples. Cooked masoor dal refrigerates well for 4-5 days and freezes for up to 3 months. Cooked dal thickens significantly when refrigerated (starch retrogradation) — add 2-3 tablespoons water when reheating and stir over medium heat.
