Technique

High‑heat grilling
Creates a caramelized, slightly smoky crust on the tuna while keeping the interior moist

Allows the juices to redistribute, preventing them from spilling out when cut

Common mistakes

  • Overcooking the tuna, resulting in a dry, tough texture
  • Using canned tuna instead of fresh steak, which ruins texture
  • Failing to emulsify the sauce, leading to separated oil and chili
  • Grilling on insufficiently high heat, causing steaming rather than searing
  • Not allowing the tuna to rest, causing juices to run out when sliced

Provenance

Grilled tuna with pepper sauce is a staple of São Tomé and Príncipe cuisine, reflecting Portuguese colonial influence and the island’s abundant tuna stocks. The dish pairs the local tradition of generous spice use—particularly the piri‑piri chili—with the Portuguese method of grilling meaty fish. It is commonly found in home kitchens and seaside restaurants across the islands.
