Using the Sauté function on High, heat the coconut oil for about 1 minute, until shimmering. Add the onions and cook for about 4 minutes, stirring occasionally, until softened.
Stir in the salt, cumin, turmeric and chili powder; cook for 1 minute, until fragrant. Add the ginger, garlic, curry leaves, and chile; cook for 2 minutes, until fragrant. Stir in the water, using a wooden spoon to scrape up all the browned pieces from the bottom of the pot. Stir in the pork and coconut milk.
Secure the lid and cook on high pressure for 30 minutes.
Once the cooking is complete, let the pressure release naturally for 5 minutes, then quick-release the remaining pressure. Remove the lid and, using the Sauté function on Low, simmer the sauce for about 3 minutes, or until it thickens a bit; it should be pretty creamy. Taste and add more salt if needed. Stir in the chopped cilantro and serve.
