Rinse the salt cod under cold water and remove as much of the salt as you can.
Place salt cod in a container and cover with cold water.
Cover container and store in refrigerator overnight to release the excess salt.
Once salt cod has been soaked overnight discard water and place salt cod in a medium pan, cover with fresh cold water and add a wedge of lime and place on a high heat.
Once water comes to a boil lower heat to a simmer and cook until you are able to flake the salt cod, then set aside to cool. Flake salt cod once cool.
Wash potatoes, cut in half and place in a medium pan.
Cover potatoes with boiled water and add a pinch of salt, cover pan and place on high heat.
Once potatoes come to a boil, lower to a simmer and cook for 8 minutes.
Prepare curry paste while potatoes are cooking.
Curry Paste
Pulse curry ingredients in a food processor or high speed blender to a paste, adding water a tbsp at a time until the paste in completely smooth then set aside.
Thai Green Curry
In a large pan heat olive oil and then add shallots and chilies and lower heat to medium. Toss until aroma begins to release and the shallots slices completely separate.
Combine curry paste with coconut milk, fish sauce and water and then add to shallots.
Add flaked salt cod and mix thoroughly.
Cover pan and lower heat to a simmer for 10 mins.
Once flavors are all nicely combined add potatoes and mix thoroughly.
Taste sauce and season as necessary.
I suggest an additional cup of coconut milk and either salt of fish sauce to taste.
Combine ingredients one final time and then simmer again for another 10 minutes.
Serve in bowls with rotis or over a bed of rice.
Notes
Make sure to blend your curry paste thoroughly. Lemongrass is woody, so you want to ensure the stalks are unrecognizable.
