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.
Cut Trout into 6 even pieces and place them into a deep tray and pour the chilled coconut marinade over the top. Leave the trout to marinade covered in the fridge over night.
The next day, place seasoned trout with salt and oil the pans. Place the trout in and leave for a minute.
In 2 large cast iron pans or regular non-stick pans over low-medium heat fry fish for about 4 minutes. Turn the heat back up and leave for 2 to 3 minutes. Take the trout out of the pan and let rest for a minute.
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. Once the shallots come out and are placed onto a paper towel, use a fork to fluff it up and then season with salt and give a light dusting of icing sugar to enhance and balance the flavor.
In a small pot placed the sliced garlic pour 200 ml of milk over the top and bring to a boil. Strain off and then run under cold water to rinse excess milk. 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.
In a medium sauce pan bring the palm sugar and water to a boil and let cool for 20 minutes before you make the dressing.
In a food processor and place in half of the fried ingredients and blitz until it is like a powder, then slowly pour in half of the palm sugar water and blitz for a minute. In a large mixing bowl pour mixture and repeat with the remainders. Add the lime juice and fish sauce and reserve on the side until needed.
In 6 separate mixing bowls, evenly divide the red onion, spring onion, chili, crab, avocado, pomelo, Thai basil, and coriander. Reserve on the side.
In a small bowl, add all the ingredients and mix well. Reserve on the side.
