A classic Thai dish that balances crispy, airy catfish with a bright, spicy green mango salad. The contrast between crunchy fish and tangy dressing is what makes Yum Pla Dook Foo so addictive.
Remove the meat from the grilled catfish, making sure there are no bones left.
Using a mortar and pestle, pound the fish until it becomes light and fluffy. (Alternatively, pulse briefly in a food processor, but make sure not to over-process.)
Spread the fish in a thin layer on a tray and dry it in a low oven (about 100–120°C / 210–250°F) until completely dry but not browned.
Set aside and let the dried fish meat cool completely.
Heat a generous amount of cooking oil over medium-high heat. Once the oil is very hot, add small handfuls of the fish meat (do not crowd the pan).
As soon as the fish floats and turns a light golden brown, scoop it out immediately and drain on paper towels.
For the Mango salad:
In a mixing bowl, combine fish sauce, lime juice, palm sugar, and seasoning powder. Stir until the sugar is completely dissolved.
Add the sliced chilies, shallots, mango, and celery into the dressing. Toss gently to combine all the flavors.
Assembly:
Place the crispy catfish on a serving plate. You can either pour the dressing over the fish just before eating or serve the salad in a separate bowl to keep the fish extra crunchy. Garnish with roasted peanuts on top.
