Place a large oven-safe pot on the stove over low heat and lightly toast the peanuts, then remove and set aside.

Add the olive oil to the pan, then brown the lamb shanks over medium-high heat. Once well browned, remove to a plate.
1 tablespoon olive oil, 4 lamb shanks
Fry the onion over low heat until it starts to soften, then add curry paste, coconut milk, beef stock, star anise and stir well to combine.
