Step 1

Preheat the Instant Pot by selecting the Sauté setting. Heat the oil in the preheated pot for a few seconds, then add the onion and a pinch of salt and cook until the onion is translucent, about 2 minutes. Add the ginger and garlic and cook for 1 minute. Stir in the pureed tomatoes, paprika, turmeric, garam masala, and remaining 3/4 teaspoon of salt and cook until almost at a boil, for about 2 minutes. Select the Cancel setting. Give it a good stir to pick up any stuck bits.

Step 2

Add the potatoes to the pot and stir to coat them in the sauce. Gently pour in the water.

Step 3

Lock the lid into place, set the Pressure Release Knob to Sealing, select the Pressure Cook/Manual setting at high pressure, and set the cook time to 9 minutes for 1-inch (2.5 cm) or smaller potatoes and 10 minutes for larger potatoes.

Step 4

Once the cooking cycle is done, let the pressure release naturally for 5 minutes, then carefully set the Pressure Release Knob from Sealing to Venting to release any remaining pressure. Open the lid.

Step 5

Stir in the cashew cream, select the Sauté setting, and cook to bring to a boil, about 2 minutes. Select the Cancel setting. Fold in the fenugreek leaves, if using. Taste for salt, adjusting if needed.

Step 6

Garnish with the cilantro.
