Prepare the toppings and sauce. Dunk the toppings in a bowl of ice cold water to keep it fresh and crunchy.
Steam the fish and sauce at the same time (in separate containers).Pro Tip: The steaming duration can vary widely depending on the size and shape of your fish and steaming equipment. Rather than rely on timing, check for these indicators instead: The eyes turn from black to white; stick a chopstick into the thickest part of fish and it should be fairly tender as you poke through; the meat should separate easily from the bones and flake off.
Pour away any fish juice that comes out of the fish, then pour the sauce onto the fish.
Heat up some oil until it shimmers. Place the toppings on the fish, pour the hot oil over it to get a nice sizzle, and it's ready to serve!
