1. Sumac is a spice with a tangy flavour that is often used in cooking or to make juice. The purple berries of this decorative bush are dried and often coarsely ground and can be found at specialty cooking stores. Lemon vinegar, like champagne vinegar and other specialty vinegar, is also available from specialty cooking stores.

2. Heat olive oil in a medium saute pan on high heat. Add tuna loins and sear for about 15 seconds on each side.
3. In a heavy-bottomed saute pan, toast fennel and coriander seeds over medium heat for 1 minute. Transfer them to a spice grinder. Add pink peppercorns and sumac and grind the spices into a fine dust.
4. In a small saucepan on medium heat, combine honey, soy sauce, five-spice powder and powdered ginger and heat for 3 to 4 minutes, until reduced by one-third. Remove from heat and allow to cool.
