Nokcha-Brined Grilled Mackerel with Scallion Rice
A nokcha tea brine tenderizes mackerel and tames its richness, while a quick scallion rice soaks up every nutty, savory drop of pan juices.
Brining fish in brewed green tea is a quiet trick used in parts of Korea and Japan to tame the strong, oily flavor of mackerel while adding a faint savory sweetness. Nokcha works especially well here because its toasted, nutty notes complement the char you get from grilling rather than fighting it.
The brine itself is simple: strongly brewed nokcha, salt, and a little sugar, cooled completely before the fish goes in. Twenty to thirty minutes is enough — any longer and the tannins can start to firm up the flesh too much.
While the fish grills, a quick scallion rice comes together using a few tablespoons of the same brewed nokcha stirred through hot steamed rice along with sesame oil and scallions. The tea's nuttiness deepens the rice's flavor in a way that's subtle but unmistakable once you taste it.
Serve the mackerel whole or filleted over the rice with a wedge of lemon and a side of quick-pickled radish. It's a weeknight dinner that leans on pantry staples but tastes like it took real technique — because the tea is quietly doing a lot of the work.
Ingredients
- 2 whole mackerel, cleaned and scored (or 4 fillets)
- 2 cups strongly brewed nokcha, cooled (4 tsp leaves steeped 4 minutes)
- 2 tbsp salt
- 1 tbsp sugar
- 2 cups cooked short-grain rice
- 3 scallions, thinly sliced
- 1 tbsp toasted sesame oil
- 1 tsp toasted sesame seeds
- 1 tbsp neutral oil for grilling
- 1 lemon, cut into wedges
- Quick-pickled radish, for serving
How to make it
- 1Brew the nokcha strong and let it cool completely. Reserve 3 tbsp for the rice and use the rest for the brine.
- 2Stir salt and sugar into the cooled tea brine until dissolved. Submerge the mackerel and refrigerate 20–30 minutes.
- 3Remove fish from the brine, pat dry, and brush lightly with neutral oil. Grill or pan-sear over medium-high heat, about 4–5 minutes per side, until the skin is crisp and flesh flakes easily.
- 4While the fish cooks, stir the reserved 3 tbsp brewed nokcha, sesame oil, scallions, and sesame seeds through the hot cooked rice.
- 5Plate the rice, top with the grilled mackerel, and serve with lemon wedges and pickled radish on the side.
