Start by siring both sides of the steaks, then remove from the pan.
To the same pan on the lowest heat add the massaman paste, brown for a minute and then add in the coconut milk and kefir lime leaves. Let this simmer whilst you chop the veggies and dice up the steak.
Add in the beef stock cube, fish sauce, diced steak and potatoes. Give this a good mix and let this simmer for 10 minutes.
Add the peanut butter, lime juice, water and the carrot and onion. Mix together and place the lid on for this to cook down for about an hour (can be done quicker but the longer the better).
Finally add in the brown sugar, stir well and cook for another 10 minutes before serving over freshly steamed rice!
Top with fresh coriander, fried onions and lime!
