Feels like he's pulled it off, but I'm not sure I could have a lot of them. You can certainly taste the game-iness of the duck, the sweet plum sauce is there but isn't too intense, and even the tang of spring onion slips through.
Other flavours? Chives, parsley, ginger, fennel and garlic. They also taste very smokey.
A good winter crisp. He's done a good job with these.
