Thekera Tenga Aloo
A tangy, comforting potato curry from Assam that gets its unique sourness from dried mangosteen. The thekera imparts a citrusy punch that perfectly balances the earthy potatoes, while minimal spices let the tart fruit shine. A homestyle dish that pairs beautifully with steamed rice.
For 4 servings
- prep · ~15 min
Soak the dried mangosteen.
Place the dried mangosteen pieces in a small bowl with warm water and let them soak for 15 minutes to soften.
- boil · ~15 min
Boil the potatoes.
Peel and cube the potatoes. Add them to a pot with 300 ml water and salt. Bring to a boil and cook until fork-tender, about 12-15 minutes. Do not drain the water.
- prep · ~2 min
Mash the soaked mangosteen.
After soaking, squeeze the softened mangosteen pieces in your fingers directly into the pot with the potatoes. Discard the fibrous seeds and hard parts. Stir well to incorporate the tangy pulp into the broth.
TIPSqueeze well — the pulp holds all the tangy, citrusy flavor that defines this dish. - simmer · ~7 min
Simmer the curry.
Let the curry simmer on low heat for 5-7 minutes, allowing the flavors to meld. The potatoes will absorb the tangy broth. Add sugar if the curry feels too sour. Lightly mash a few potato cubes against the side of the pot to thicken the gravy slightly.
- temper · ~1 min
Temper with mustard oil and green chili.
In a small tempering pan, heat mustard oil until it reaches its smoking point. Remove from heat briefly, then add the slit green chilies and let them sizzle for 10 seconds. Pour this tempering over the simmering potato curry and cover immediately to trap the aroma.
TIPHeating mustard oil to its smoke point removes its raw pungency and gives a mellow nutty flavor. - rest · ~2 min
Rest for 2 minutes, then serve.
Keep the pot covered for 2 minutes. Serve hot with steamed rice.
