Dal Tadka with Garlic Tarka

📅 February 28, 2025 🌱 Vegetarian 🌶 Medium heat ⏱ 55 minutes

Dal tadka is one of the most complete, satisfying meals in any culinary tradition. Red lentils cooked down with aromatics until thick and porridge-like, then — at the very last moment — hit with a ladleful of sizzling spiced ghee poured over the surface. The sound it makes when the tarka meets the dal is part of the experience.

The word tadka (also written tarka) refers to the technique of blooming whole spices in hot fat before adding them to a dish. The fat is the delivery mechanism — fat-soluble flavour compounds in the spices dissolve into the ghee and then distribute through the dal when stirred in. The result is an intensity of flavour that adding spices directly to water could never achieve.

Which Lentils to Use

Red split lentils (masoor dal) are the standard for this recipe. They cook quickly, break down completely, and produce a smooth, silky texture without any soaking. Yellow split lentils (chana dal or toor dal) can also be used for a slightly denser, earthier result, but require longer cooking. Do not use green or brown lentils here — they hold their shape and produce a completely different texture that doesn't suit the dish.

Ingredients — Dal

  • 300g red split lentils, rinsed until water runs clear
  • 1.2 litres water
  • 1 tsp ground turmeric
  • 1 tsp fine salt (plus more to taste)
  • 2 tbsp ghee or neutral oil
  • 1 large onion, finely diced
  • 4 cloves garlic, minced
  • 1 tbsp fresh ginger, grated
  • 2 medium tomatoes, finely chopped
  • 1 tsp ground cumin
  • 1 tsp ground coriander
  • ½ tsp chilli powder (adjust to taste)

Ingredients — Tarka

  • 3 tbsp ghee
  • 6 cloves garlic, thinly sliced
  • 1 tsp cumin seeds
  • ½ tsp mustard seeds
  • 2 dried red chillies
  • A pinch of asafoetida (hing) — optional but excellent
  • 1 tsp sweet or smoked paprika

To Serve

  • Basmati rice or warm roti/naan
  • Fresh coriander leaves
  • Lemon or lime wedges

Method

  1. 1
    Put the rinsed lentils in a large saucepan with the water, turmeric, and salt. Bring to a boil, skim off any foam, then reduce to a steady simmer. Cook uncovered for 25–30 minutes, stirring occasionally, until the lentils have completely broken down and the mixture is thick and porridge-like. Add more water if it becomes too thick.
  2. 2
    While the lentils cook, heat 2 tbsp ghee in a frying pan over medium heat. Add the diced onion and cook for 12–15 minutes, stirring regularly, until it is soft, deeply golden, and beginning to caramelise at the edges.
  3. 3
    Add the garlic and ginger to the onions and cook for 2 minutes until fragrant. Add the chopped tomatoes, cumin, coriander, and chilli powder. Cook, stirring, for 5–6 minutes until the tomatoes have broken down and the mixture looks like a rough paste.
  4. 4
    Stir the onion-tomato mixture into the cooked lentils. Taste for salt and adjust. Keep warm on a low heat while you make the tarka.
  5. 5
    Make the tarka: Heat the 3 tbsp ghee in a small frying pan over medium-high heat. When it shimmers, add the mustard seeds and cumin seeds. When they pop and sizzle (about 30 seconds), add the sliced garlic and dried chillies. Cook for 60–90 seconds until the garlic is golden (not dark). Add the asafoetida if using, then the paprika. Stir once.
  6. 6
    Immediately pour the hot tarka over the dal. It will sizzle dramatically. Stir it through halfway, leaving some on top for visual effect. Serve over rice with coriander and a wedge of lemon.
💡 The tarka: Speed is important when making the tarka — garlic goes from golden to burnt very quickly. Have everything measured and ready before you heat the ghee. The whole process takes under two minutes once the fat is hot.

Getting the Consistency Right

Dal tadka should be thick enough to mound slightly on a spoon but still pourable. Thinner than pea soup, thicker than stock. If it becomes too thick during cooking, add water a ladleful at a time. It will thicken considerably as it cools, so err on the side of slightly loose when it's hot.

Making It Vegan

Substitute neutral oil (sunflower or refined coconut) for the ghee throughout. The flavour will be slightly less rich but otherwise the recipe is entirely plant-based. The tarka is the area where ghee makes the biggest difference — its high smoke point allows the spices to bloom properly without risk of burning.
