Switch on instant pot and press the saute button, allow it to heat. Add oil and cinnamon stick, saute well. Add cumin or jeera, fry well until you get nice aroma.
As cumin changes light brown and becomes aromatic, add finely chopped garlic pods and onion. Fry them well until everything gets lightly brown.
Add finely chopped tomatoes with half cup water. This water helps in cooking tomato and prevents sticking to the bottom of pot.
Cook the tomatoes to make it mushy for 2 to 3 minutes with continuously frying. Add coriander powder, red chili powder and salt. Mix everything well.
Next add soaked rinsed matki and garam masala. Mix everything and add 1 ½ cup water. Deglaze the mixture to prevent sticking at the bottom of pot.
Close the instant pot lid and seal the pressure value. Set the Instant pot at high pressure for 10 minutes.
It takes few minutes for pressure to build and then timer begins. After 10 minutes, wait for 5 to 6 minutes and give a quick pressure release (QPR).
As the steam releases, knob comes down, open the lid carefully and the matki masala curry is ready. Finish off the curry with some finely chopped coriander leaves.
I have not added any lemon juice in this recipe. Since the quantity of tomatoes mentioned in the recipe is perfect to balance the tangy flavours to matki masala curry.
However, if you still wish for some more tanginess, can always add squirts of lemon.
When we open the lid, the curry seems to be watery, however as they cool slightly these lentils get creamy and thick making them perfect as side dish.
