House-Smoked Eomuk (Korean Fish Cake)

Begin by chilling 1.5 lbs of firm white fish (pollock or cod) until it is near-freezing but not solid. Place the cold fish into a food processor and pulse until it begins to break down, then add 1 egg white, 3 tbsp potato starch, 2 tbsp mirin, 1 tbsp sugar, 1 tbsp grated garlic, 1 tsp grated ginger, and 1 tsp salt. Process on high for 2-3 minutes until the mixture transforms into a homogenous, sticky, and highly elastic paste; this friction-sensitive process requires the fish to stay below 40°F to ensure the proteins emulsify correctly rather than breaking.

Transfer the fish paste to a chilled mixing bowl and add 0.25 grated onion (squeezed dry to remove excess moisture) and 2 minced scallions. Use a spatula to fold these aromatics into the paste by hand until evenly distributed, taking care not to overwork the mix which could introduce too much air and create a spongy rather than dense cake.

Lightly coat your hands and a parchment-lined tray with neutral oil to prevent sticking. Portion the paste into balls and flatten them into oval cakes approximately 1/2 inch thick; uniform thickness is critical for even heat penetration in the smoker. Aim for consistent shapes to ensure they all reach the food safety threshold simultaneously.

Place the formed cakes on a wire cooling rack and let them rest uncovered in a cool, breezy area (or refrigerated) for 30 minutes. This air-drying phase allows the proteins on the surface to knit together into a tacky layer called a pellicle; this layer is what the smoke compounds will bond to, providing the deep bronze color and smoky flavor.

Preheat your smoker to 225°F using alder or apple wood; these delicate woods are chosen because their mild, slightly sweet phenols complement the lean white fish without overpowering the ginger and mirin. Ensure you have a clean, blue smoke rolling before adding the fish cakes to avoid depositing bitter creosote on the delicate protein.

Arrange the cakes on the grates with at least one inch of space between them to allow for total airflow. Smoke at 225°F for 30 to 35 minutes until the cakes feel firm to the touch and spring back when pressed; use an instant-read thermometer to verify an internal temperature of 145°F, passing the food safety threshold for seafood while maintaining moisture.

Remove the cakes from the smoker and let them rest on a wire rack for 10 minutes. During this time, the internal temperature will stabilize and the starch will fully retrograde, locking in the juice and ensuring the cakes maintain their shape when sliced or added to hot broths like eomuk-tang.

The finished eomuk can be served warm as a snack, sliced into strips for a spicy stir-fry with gochugaru and soy, or threaded onto skewers for a traditional fish cake soup. If not using immediately, cool completely and refrigerate; the smoke flavor will actually intensify and mellow over the first 24 hours in the fridge.
