Delicious! I have one suggestion. When I was in Nepal a year ago, I watched someone make this recipe, only minus the cilantro (a delicious variation!) and I think with some red pepper.
To make the flavor go all the way through the potatoes, she simply fried cut raw potatoes with the spices, and at least 4 Tbls of oil, for about 5 minutes and then added water and then pressure cooked everything together. The flavor went all the way through the potatoes! I have done this with just a covered pot and let it cook longer.
Glad this great dish is on the site!
