Notes

Instant Pot
Sauté the onions & curry paste, deglaze the pan well with the stock, add all ingredients, and pressure cook on high pressure for 5 minutes with a 10 minute natural pressure release. Puree and add in the coconut and lime juice after cooking. A double batch of this soup fits well in the 8 quart Instant Pot.
