Ennai Kathirikai: Brinjal Curry for Biryani

What is ennai kathirikai?

Ennai means oil and kathirikai means brinjal in Tamil, and the name describes the method as much as the dish: small eggplants are stuffed with a roasted, ground masala and cooked slowly in oil and tamarind until they turn soft and glossy. It belongs to the kuzhambu family, the broad group of Tamil tamarind-based gravies, and the stuffed-eggplant version is one of its best known variants, usually served as a side for rice. In practice, in most Tamil Muslim kitchens, it is the side dish that goes next to biryani before anything else gets considered, because tamarind and peanut cut through rich, ghee-heavy rice in a way a plain raita cannot. It shows up most often alongside the styles covered in our guide to South Indian biryani styles, particularly the Tamil Nadu ones built on seeraga samba rice and a slow dum.

Choosing and prepping the brinjals

Small, round violet brinjals are the right pick, not the long, pale variety used for a poriyal or a roast. They should feel firm and heavy for their size, with a stem that is still green and slightly moist, a sign they were picked recently rather than sitting on a shelf. Wash them just before cooking rather than in advance, cut brinjal browns quickly once exposed to air, so slit and stuff them close to when they go into the pan. If you cannot find the small round variety, the smaller Thai-style green or striped brinjals work as a substitute, keep the same golf-ball size so the cooking time in the method below still holds.

Ingredients

• 10 to 12 small brinjals (round violet or Thai-style, about the size of a golf ball)
• 3 tablespoons raw peanuts
• 2 tablespoons white sesame seeds
• 1 teaspoon cumin seeds
• 4 to 5 dried red chillies
• 1 inch cinnamon stick
• 2 cloves
• 2 tablespoons tamarind, soaked in 120 ml warm water
• 3 tablespoons gingelly (sesame) oil
• 1 teaspoon mustard seeds
• 1 sprig curry leaves
• 1 medium onion, finely chopped
• 1 medium tomato, chopped
• 1/4 teaspoon turmeric powder
• 1 teaspoon jaggery
• Salt to taste

Method

Make the masala

Dry roast the peanuts in a pan on medium heat for about 3 minutes until the skins darken slightly, then set aside. In the same pan, dry roast the sesame seeds for 1 minute until they turn a shade darker and smell toasted. Add the cumin seeds, dried red chillies, cinnamon and cloves and roast for another 2 minutes until fragrant. Cool for 2 minutes, then grind to a coarse powder using the dry grinding blade, no water at this stage.

Stuff the brinjals

Wash the brinjals and slit each one into quarters from the bottom, keeping the stem end intact so the pieces stay attached and hold their shape. Stuff each brinjal generously with the ground masala, using about three quarters of it, and set the rest aside for the gravy. This takes about 7 minutes for a full batch.

Extract the tamarind

While you stuff the brinjals, soak the tamarind in 120 ml warm water for 10 minutes, then squeeze it through your fingers and strain out the fibre. You should have a thick, dark extract.

Build the gravy

Heat the gingelly oil in a wide pan on medium heat. Add the mustard seeds and let them splutter, about 1 minute, then add the curry leaves. Add the chopped onion and saute for 4 minutes until it turns translucent and just starts to colour at the edges. Add the tomato and cook for 3 minutes until it breaks down and turns soft.

Simmer and finish

Stir in the turmeric, the reserved masala and the tamarind extract, and let it bubble for 2 minutes so the raw tamarind smell cooks off. Lower the stuffed brinjals gently into the gravy, add salt and the jaggery, cover, and cook on low heat for 15 minutes, turning the brinjals gently once halfway so they cook through without breaking apart. The curry is done when the brinjals are soft all the way through and a thin layer of oil sits visibly at the edges of the pan. Rest for 5 minutes before serving.

What to serve it with

This is built to sit next to a meat biryani, an Ambur or a Dindigul style in particular, where the sourness and peanut body cut the richness of a ghee-and-spice rice. Our comparison of Ambur vs Dindigul biryani covers exactly how those two styles differ if you are deciding which one to cook alongside this curry. It also holds up well next to a wedding-style biryani, where a table usually carries two or three sides rather than one. See our full guide to what to serve with biryani for the rest of the spread, including raita and dalcha.

Scaling this recipe up for a party

The ratios here hold at any scale: for every 10 to 12 brinjals, keep the peanut, sesame and tamarind quantities as listed and simply repeat the batch rather than doubling everything in one pan, a wider gravy is harder to reduce evenly than two batches cooked one after another. If you are planning the rest of the meal at the same time, our guide to biryani quantity per person works out exactly how much rice, protein and paste you need for 10, 25, 50 or 100 guests, so the brinjal curry batch size lines up with the biryani rather than running short or making far too much.

Notes on the less obvious ingredients

Gingelly oil, cold-pressed sesame oil, is what most Tamil kitchens use for this curry specifically, its slightly nutty edge works with the peanut and sesame in the masala in a way a neutral sunflower oil does not. If you cannot find it, a light sesame oil blended with a neutral oil is a reasonable substitute, just avoid a strongly toasted, dark sesame oil, it will overpower the tamarind rather than support it. Jaggery is there to round off the tamarind's sharpness, not to make the curry sweet, a teaspoon is usually enough, add a second only if the tamarind you are using is unusually sour. Curry leaves lose their fragrance fast once dried, so fresh is worth seeking out here rather than substituting the dried version most spice racks keep on hand.

Common mistakes with this curry

The most common one is rushing the roast, an under-roasted peanut and sesame masala tastes raw and slightly bitter no matter how long the curry simmers afterward, so give the roasting stage the full time even if it feels slow. The second is using too much water in the gravy, this is meant to be a thick, clinging curry rather than a thin one, if it looks watery after the brinjals go in, uncover and let it reduce for a few extra minutes rather than adding more tamarind to compensate. The third is stirring the pot too often once the brinjals are in, they are more fragile than they look once slit and stuffed, and frequent stirring breaks them apart before the masala has had time to set inside.

Storage

Ennai kathirikai keeps well, arguably better than the biryani itself. Refrigerate it in an airtight container and it holds for 3 to 4 days, and the tamarind base means it often tastes even better on day two once the flavours settle. Reheat gently on the stove with a splash of water rather than in the microwave, so the brinjals do not turn mushy.

Frequently asked questions

Can I make ennai kathirikai without peanuts?

Yes, increase the sesame seeds by a tablespoon to make up the body, though the curry will taste slightly less rounded. Do not skip the tamarind, it is what makes the dish work as a biryani side.

What brinjals work best for this recipe?

Small, round violet brinjals or the smaller Thai-style ones. Avoid the large, long variety, they need more gravy per piece and tend to fall apart before the masala cooks through.

Can I make this ahead for a party?

Yes, and it is one of the few Indian sides that genuinely improves resting overnight in the fridge. Make it the day before and reheat gently before serving.

Is ennai kathirikai spicy?

Moderately, from the dried red chillies in the masala. Reduce to 2 or 3 chillies if you are serving it alongside an already spicy biryani like Nellore or Andhra style.

Can I use this recipe as a plain side without biryani?

Yes, it works equally well with plain rice, curd rice or chapati. It is a kuzhambu at heart, and kuzhambu was built to go with rice long before it ever met biryani.
