I replaced the tuna with salmon in this fresh spring salad.
Maltose, also called malt sugar. Mostly brown viscous syrup that is used when lacquering Peking duck. The duck is doused several times with this sugar (in slightly heated form to become more liquid), giving it its brown color. Maltose is also used in marinade's for example Char Siu (Eastern red BBQ pork). I add them directly to marinade which makes the dish caramelize at BBQ time. You can also simply stick it on the meat afterwards, giving it a nice shine.
