Rinse the pangasius fillets thoroughly under cold water and place them in a deep bowl, gently patting them dry with paper towels. Add sweet paprika, curry, black pepper, salt, and 2 tablespoons of olive oil. Gently massage with your hands to ensure the spices penetrate every part of the fish. Cover the bowl with plastic wrap and let it marinate in the refrigerator for at least
1 hour.
