Khatti Dal (Spiced Tamarind Pigeon Peas)

Introduction

Khatti dal is a tangy, spiced pigeon pea curry built on tamarind’s sharp backbone and finished with a tempering of mustard and cumin seeds. The dish comes together in about 45 minutes total and works equally well as a weeknight dinner side or a make-ahead lunch that tastes better the next day.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 30 minutes
• Total Time: 45 minutes
• Servings: 4

Ingredients

• 1 cup (240 ml) toor daal (split pigeon peas)
• 2 tbsp oil
• 1 onion
• ½ tsp ginger paste
• 1 tsp garlic paste
• 3 tbsp diced or crushed tomato
• 6-8 pieces whole tamarind
• 1 tsp red chilli powder
• ½ tsp turmeric
• 1 tsp mustard seeds
• 1 tsp cumin seeds (jeera)
• Curry leaves
• Salt to taste
• Coriander leaves (cilantro) for garnish

Instructions

1. Wash toor daal and boil for about 20 minutes until soft. Drain and smash the dal.
2. In a kadai, heat the oil until hot. Add curry leaves, mustard seeds and jeera seeds. Fry for a minute. They will pop at first, so a cover will help to avoid a mess.
3. Add onion and fry until slightly brown.
4. Add ginger and garlic paste. Fry for a minute, then add the tomatoes. Cook until the oil separates.
5. Add tamarind pieces, turmeric powder, and red chilli powder. Cook it for 4-5 minutes.
6. Add the toor daal and enough water for your desired thickness.
7. Add salt to taste, and garnish with coriander leaves.
8. Serve with a roti or poured over rice.

Variations

Adjust the tamarind level. If you prefer a less sharp tang, reduce the tamarind pieces to 4–5; for more sourness, add up to 10 pieces. The depth of the dish shifts noticeably with this change.

Add vegetables. Stir in diced carrot, bell pepper, or green beans during the final water addition. They’ll soften into the curry and add texture without changing the core flavor.

Make it spicier. Increase the red chilli powder to 1½ tsp or add 1–2 green chillies, minced, when you add the ginger and garlic paste.

Cook it thinner. Add extra water (½ to 1 cup more) after the dal goes in to create a soupy consistency that works better poured over rice rather than served as a thicker side.

Use split red lentils instead. Substitute masoor daal for toor daal in equal measure. The flavor will be milder and the texture slightly creamier, though the tamarind and spice backbone remains strong.

Tips for Success

Don’t skip the tempering step. The mustard and cumin seeds fried in hot oil are the signature flavor base; rushing or skipping this step flattens the entire dish.

Mash the dal thoroughly. After boiling, break down at least half the pigeon peas so the curry has body and clings to the spices; leaving them whole makes it too brothy.

Watch for oil separation. Once you add tomatoes in step 4, cook until you see a thin layer of oil pooling around the tomato solids—this signals the flavors have melded and you’re ready for the tamarind.

Taste and adjust salt last. Add tamarind pieces and spices first, let them meld for a few minutes, then taste before salting; tamarind’s sourness can mask saltiness, so you may need less than you expect.

Cover the pan during tempering. The mustard and cumin seeds will pop and splatter hot oil; a lid or splatter screen keeps your stovetop clean and you safe.

Storage and Reheating

Reheat on the stovetop over medium heat, stirring frequently and adding a splash of water if it has thickened too much. Microwave reheating works in a pinch (covered, 2–3 minutes, stirring halfway), but stovetop gives the best texture and allows you to adjust the consistency.

FAQ

Can I use canned tamarind paste instead of whole pieces?

Yes—use 2 tbsp tamarind paste mixed into a little water, and add it at the same point in the recipe. The flavor will be slightly less mellow, so taste and reduce if it becomes too sour.

What if I can’t find toor daal?

Yellow split peas or split red lentils work as substitutes in the same quantity. Yellow peas will give a closer flavor; red lentils cook faster (about 12–15 minutes) and create a creamier consistency.

How do I know if the tamarind has softened enough?

The pieces should break apart easily when pressed against the side of the pan with a spoon. If they’re still hard after 4–5 minutes of cooking, they won’t dissolve properly into the dal.

Can this be made ahead and reheated?

Yes—prepare the entire dish, cool it completely, and refrigerate. Reheat gently on the stovetop, adding water as needed to restore the original consistency. Fresh cilantro should be added just before serving, as it wilts if mixed in and stored.
