Heat ½ cup oil in saute mode (medium heat) and add your whole spices
When they sputter and smell toasty add your onion and green chilies and cook till the edges of the onion are golden
Now add your ginger and garlic paste, saute for a minute
Add the spices, give it a quick mix
Stir in the beef, sauteeing until the beef cubes are evenly browned.
Stir in your tomatoes, dried plums (if using), and 2 cups hot water.
Pressure cook (manual) for 14 minutes
Quick release then add the potatoes and cook for another 3 minutes (4 if your potatoes usually take a long time to cook)
Quick release and then saute to dry up the excess liquid - I like to remove my potatoes here and add them back in later to avoid breaking them. The masala should be so dry that it starts to stick to the bottom and the oil rises to the top.
Taste and adjust seasoning - you want a little salty and a little spicy - if you have not used dried plums add lemon juice at this point.
