Pressure Cooking Tips:
Potatoes cook roughly in the same time as rice; that would be your guide for cooking time.
I always pressure cook potatoes, either in a pressure cooker or now, in the Instant pot. In the pressure cooker, it cooks in roughly 8 mins. With the instant pot, through experimenting with different times, I found that the rice setting (12 mins by default) cooks it perfectly for this curry, with letting it drop pressure naturally (NPR). QPR or quick pressure release left the potatoes partly undercooked in spots, and resulted in the curry being a bit hard in parts.
(If you want it to hold its shape for the potato roast, cook it about 2 minutes less or do a quick pressure release and don't let it sit to release pressure naturally.)

This is a very simple curry to make, and except for the tempering ingredients, you get everything in a regular store.
I like this curry dry, but my husband likes it a bit runny, so we compromise and settle for an in-between texture.
Great for Sunday brunches!
