Equipment

  • Medium saucepan
  • Whisk
  • Large frying pan

Ingredients
 

Mahi Mahi:

  • 4 Mahi Mahi fillets
  • kosher salt as needed
  • black pepper as needed
  • 3 tablespoons olive oil

Vanilla Sauce:

  • 1/2 cup dark rum
  • 1 vanilla bean, sliced open lengthwise
  • 1/4 cup unsalted chicken stock
  • 1 cup heavy cream
  • 1 cup coconut milk
  • kosher salt as needed

Instructions
 

Build the aromatic base

  • Set a medium saucepan over medium-high heat and pour in the dark rum with the split vanilla bean. Let it simmer for 3 to 5 minutes until it cooks down to about 2 tablespoons, allowing the alcohol smell to soften into a deeper, more fragrant aroma.
  • As it reduces, keep an eye on the pan so the liquid does not evaporate completely. You want a concentrated base that pulls the aromatic oils from the vanilla pod without scorching the sugars in the rum.

Whisk and reduce the sauce

  • Slowly add the chicken stock, heavy cream, and coconut milk while whisking steadily, ensuring everything blends into one smooth mixture. This gradual addition helps the dairy and rum come together cleanly instead of turning grainy.
  • Lower the heat enough to keep the sauce at a gentle simmer, then whisk continuously for about 15 minutes. When it is ready, the sauce should reduce to a thick, silky consistency that clings to the back of a spoon instead of running off in a thin stream.

Finish the emulsion and cook the fish

  • Turn off the heat and lift out the vanilla pod carefully. Scrape the seeds from the pod back into the warm sauce, whisk them in, then immediately whisk in 1 tablespoon of cold unsalted butter until the sauce looks glossy and unified. Add a few drops of fresh lime juice, season with kosher salt to taste, and keep the sauce warm for serving.
  • Pat the Mahi Mahi fillets dry, then season both sides with kosher salt and black pepper. Dry fish surfaces sear far better, resulting in a beautiful golden crust.
  • Heat the olive oil in a large frying pan over medium-high heat until it looks hot and fluid. Add the fillets and sear for about 3 to 4 minutes per side, turning once, until the outside is golden brown and the flesh is opaque all the way through.

Plate and serve

  • Transfer the pan-seared fish to serving plates and spoon the warm vanilla sauce generously over the top. The finished dish should smell floral and buttery, with a lush sauce that settles around the fish perfectly.

Notes

Aromatic Tip: Simmer the split vanilla pod directly in the rum first to pull out maximum flavor before scraping in the seeds at the end.
Temperature Control: Keep the sauce at a gentle simmer rather than a rolling boil to prevent the heavy cream and coconut milk from separating and breaking the emulsion.
Storage Tip: Leftover cooked fish and sauce can be refrigerated in separate airtight containers for up to 2 days. Reheat the sauce gently over very low heat to prevent splitting.
