Warm the wok's oil (ensure that the oil is no more than halfway up the wok).
Deep fry the fish for 5 to 6 minutes at a temperature of 350 degrees Fahrenheit, or until golden brown. Remove from the oil, then drain on a platter covered with paper towels.
Thai chili peppers are roughly ground in a pestle and mortar to create the salsa dressing. Put the peppers in a salad bowl.
Fish sauce adds salt, sugar adds sweetness, and lime juice adds sourness to the dressing.
In the salad bowl, combine the mango, shallots, lemongrass, coriander, and spring onions.
Pair the crispy fish with the mango salad.
