Ingredients

Black Garlic Marinade (Skip this if using pre-marinated black garlic tuna)
  • 2 tbsp neutral oil (canola preferred)
  • 1 tsp soy sauce
  • ½ tsp kosher salt
  • 1 tsp black garlic, mashed to a paste
  • ¼ tsp garlic powder
  • ¼ tsp onion powder
  • ½ tsp dehydrated onion (minced, optional but ideal)
  • 1 tsp brandy vinegar (or red wine vinegar + a pinch of sugar)
  • ⅛ tsp turmeric
  • ⅛ tsp sugar
  • ⅛ tsp ground spice (white pepper or coriander)

Tuna Confit
  • 1 lb ahi / yellowfin tuna steak
  • Marinade from above (if using)
  • ½–¾ cup extra-virgin olive oil (enough to mostly submerge)

Rillettes
  • 1–2 tsp toasted sesame oil (to taste)
  • 1–2 tsp fresh lemon juice
  • 2–3 green onions, finely sliced (white + green parts)
  • 2–4 tbsp reserved confit oil
  • Freshly ground black pepper, to taste

Optional garnish
  • Lemon zest
  • Toasted sesame seeds

Directions

  • Mix all marinade ingredients into a loose paste.
  • Coat tuna lightly on all sides.
  • Marinate for 30–60 minutes in the refrigerator.
  • Gently blot excess marinade before cooking.
  • Heat water bath to 121°F.
  • Place tuna in a vacuum bag or zip-top bag with olive oil (tuna should be mostly submerged).
  • Seal and cook for 30 minutes.
  • Remove tuna and let cool slightly. Reserve the oil, straining before use.
  • Transfer tuna to a bowl and gently flake with two forks. Aim for small chunks, not a paste.
  • Add sesame oil, lemon juice, and sliced green onions.
  • Stir in 2–4 tbsp reserved confit oil until the mixture becomes cohesive and spreadable.
  • Season with black pepper and adjust salt if needed.
  • Chill for at least 1 hour (overnight is excellent).
  • Serve cool but not ice-cold.

  • Serve with toasted baguette or sourdough, rice crackers or sesame flatbread, endive leaves or cucumber rounds.
  • The rillettes can be stored in the refrigerator for up to 3 days.
