Cut the salmon into bite-sized pieces (about half the size of a nugget) and ensure all pieces are roughly the same size.
Combine soy sauce, minced garlic, and five-spice powder. Pour over the salmon and mix well to coat. Marinate for at least 30 minutes.
Add tapioca starch to the salmon and coat each piece evenly.You should see uneven, lumpy bits on the surface—that’s the texture we want!
Deep-fry the salmon at 175°C until lightly browned. Remove from oil.
Increase the temperature, and fry a second time until golden brown and crispy. Remove and drain.
Turn off the heat and use the residual oil to fry the basil leaves until crispy, about 10 seconds. ⚠️ Note: Stay alert and keep a safe distance — the moisture in the leaves may cause the oil to splatter.
Place the fried salmon and crispy basil leaves in a large bowl. Sprinkle with salt and pepper seasoning and gently toss until the salmon is evenly coated.
Serve immediately while hot and crispy.
