Haddock with Lime-Cilantro Butter — The Coriander Revelation That Changed Everything

January 2024. Tyler's wedding is five weeks away. I have entered full logistics mode. The rented smoker in Odessa is reserved — a large offset, 500 gallons, big enough for four briskets and three racks of ribs simultaneously. I've talked to the rental company twice, confirmed the delivery address (Tyler's house), confirmed the wood (oak, which they're providing, and pecan, which I'm bringing from Houston because I don't trust West Texas pecan). I have a spreadsheet. Bobby Tran has a spreadsheet. The world has shifted on its axis.

The brisket order is in: four prime-grade packers from my butcher on Bellaire, each weighing between fourteen and sixteen pounds. I'm picking them up Wednesday before the trip. They'll marinate in the fish sauce lemongrass rub during the five-hour drive. By the time I reach Midland, they'll have been brining in the cooler for five hours, which is not ideal (twelve hours is optimal) but I'll let them brine overnight in Tyler's fridge and start the cook at 4 AM Friday. Math checks out. Barely.

Emma brought Ava over Saturday. Ava is five months old and trying to roll over, which means she lies on her back and rotates her body forty-five degrees and then gets stuck and makes a sound that is either frustration or determination. Bobby Tran knows this sound. Bobby Tran has been making this sound his whole life. She is my blood. She will eventually roll over. And when she does, it will be the greatest athletic achievement in the history of this family, and I include Tyler's Little League home runs.

Made a test brisket for the wedding — not the full-size packers, but a flat that I picked up to calibrate my rub ratios. The rub: fish sauce, lemongrass paste, garlic, black pepper, brown sugar, and a new addition — a tablespoon of coriander seed, ground fresh. The coriander adds a lemony brightness that lifts the whole profile. I smoked it for twelve hours over oak and sliced it and tasted it and sat down and exhaled. This is the brisket. This is the one for Tyler's wedding. The coriander was the missing piece. Five years of making this rub and it was the coriander all along. Some discoveries take time. Most discoveries take time.

That moment when the coriander clicked — when I sliced the test flat, tasted it, and sat down and just exhaled — I kept thinking about brightness, about that lemony lift that had been missing from the rub for five years. Cilantro is the fresh expression of that same plant, and lime does for fish what coriander does for smoked beef: it cuts through the richness and makes everything taste more like itself. So while the wedding brisket rested in my head for the next five weeks, this haddock with lime-cilantro butter became my weeknight way of chasing that same revelation — same flavor family, twenty minutes instead of twelve hours.

Haddock with Lime-Cilantro Butter

Prep Time: 10 minutes | Cook Time: 12 minutes | Total Time: 22 minutes | Servings: 4

Ingredients

  • 4 haddock fillets (about 6 oz each), patted dry
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • 1/4 teaspoon ground coriander
  • 1 tablespoon olive oil
  • 3 tablespoons unsalted butter, divided
  • 3 cloves garlic, minced
  • Zest and juice of 2 limes
  • 1/4 cup fresh cilantro, roughly chopped
  • Lime wedges, for serving

Instructions

  1. Season the fish. Pat haddock fillets thoroughly dry with paper towels. Season both sides evenly with salt, pepper, and ground coriander.
  2. Sear the fillets. Heat olive oil and 1 tablespoon of the butter in a large skillet over medium-high heat until the butter foam subsides. Add the fillets and cook undisturbed for 4–5 minutes until a golden crust forms. Flip carefully and cook another 3–4 minutes until the fish flakes easily with a fork. Transfer to a warm plate.
  3. Build the cilantro butter. Reduce heat to medium-low. Add the remaining 2 tablespoons butter to the same pan. Once melted, add minced garlic and cook, stirring, for 60 seconds until fragrant but not browned.
  4. Add lime and cilantro. Remove the pan from heat. Stir in lime zest, lime juice, and chopped cilantro. The sauce will sizzle and tighten slightly — that’s exactly what you want.
  5. Plate and serve. Spoon the lime-cilantro butter generously over each fillet. Serve immediately with extra lime wedges on the side.

Bobby Tran was born in a refugee camp in Arkansas to parents who fled Saigon with nothing. He grew up in Houston straddling two worlds — Vietnamese at home, Texan everywhere else — and learned to cook from his mother's pho and a neighbor's BBQ smoker. He's a former shrimper, a recovering alcoholic, a divorced dad of three, and the guy who marinates brisket in fish sauce and lemongrass because he doesn't believe in borders, especially when it comes to flavor.
