In a medium pot over medium-high heat combined 2 tins (800 ml) of coconut milk, lemongrass, ginger, lime leaves, green chilies, and the fish sauce. Bring the mixture to a boil. Once boiled, remove from the heat and let cool.

In a wok on medium heat with 2 liters of peanut oil and bring up to between 160 degrees-180 degrees C. Place the chilies into the wok and fry for around 20 seconds. Take out and place on paper towel to dry. Then fry the shallots.

Then put the garlic into a clean small pot and pour in cold oil to cover an inch above. Place on high heat and bring it to a boil quickly. Turn it to medium heat and let cook until garlic is ready. Once it starts to turn a light golden, stand by it and have a strainer and a container ready that is not going to melt when you strain off the hot oil. Lay out on a paper towel.
