Salmon Burger with Hoisin Barbecue Sauce and Pickled Ginger and Napa Slaw

From Bobby Flay's Burgers, Fries, and Shakes, page 71.

Serves 4.

This burger is possibly one of my favorites from Bobby Flay's cookbook.  It combines really great flavors for a unique and tasty Asian-style burger.

Hoisin Barbecue Sauce
2 Tbs. canola oil
2 large shallots, coarsely chopped
2 cloves garlic, coarsely chopped
1/2 cup hoisin sauce
2 Tbs. ketchup
2 Tbs. honey
2 tsp. soy sauce
2 tsp. fish sauce
1 Tbs. rice wine vinegar

Salmon Burgers

1 1/2 lbs. fresh salmon

2 Tbs. canola oil

Kosher salt and freshly ground black pepper

4 hamburger buns, split; toasted, if desired

Slaw
2 Tbs. canola oil
1/4 cup sliced pickled ginger, plus more for garnish if desired
2 cloves garlic, finely chopped
1/4 small head of red cabbage, finely shredded
1/2 medium head of napa cabbage, finely shredded
Kosher salt and freshly ground black pepper
1/4 cup rice wine vinegar
2 tsp. toasted sesame oil
3 Tbs. finely chopped fresh cilantro leaves

To make the hoisin barbecue sauce, heat the oil in a medium saucepan over medium heat.  Add the shallots and garlic and cook until soft, about 2 minutes.  Add the hoisin, ketchup, honey, soy sauce, fish sauce, and vinegar and cook until heated through and slightly thickened, about 10 minutes.  Set aside to cool.  The sauce can be made 1 day in advance, covered, and refrigerated.  Bring to room temperature before using.

To form the burgers, cut the salmon into large pieces and then coarsely chop in a food processor.  Do not over-process.  (Alternatively, you can chop it by hand with a sharp knife.)  Divide the salmon into 4 equal portions.  Form each portion loosely into a 3/4"-thick burger and make a deep depression in the center with your thumb.  Place on a plate, cover with plastic wrap, and let chill in the refrigerator for at least 30 minutes before cooking.

Meanwhile, make the slaw by heating the oil in a large saute pan over high heat.  Add the ginger and garlic and cook, stirring once, until soft, about 1 minute.  Stir in the cabbage, season with salt and pepper, and cook, stirring once, until slightly wilted, 3 to 4 minutes.  Remove from the heat and stir in the vinegar, sesame oil, and cilantro.  Let sit at room temperature.

To cook the burgers, heat the oil in a saute pan or griddle (nonstick or cast iron) until it begins to shimmer.  Season both sides of each burger with salt and pepper.  Cook the burgers until golden brown on the bottom sides, about 3 minutes.  Turn over, brush with some of the hoisin barbecue sauce, and continue cooking until medium-well, about 3 minutes longer.

Place the burgers on the bun bottoms, drizzle some hoisin barbecue sauce over them, and top with the slaw.  Garnish with pickled ginger, if desired.  Cover with burger tops and serve immediately.

Notes:
- I used frozen salmon, and it still tasted great.  So use what you've got!  If you're in a hurry and all you've got are frozen salmon patties, you could probably even use them (though I doubt it would be quite as good).
- Be very, very careful not to turn your salmon into paste.  If you use a food processor, I recommend looking over the instructions for chopping meat prior to doing it so you have an idea of how long to pulse the meat.
- I don't know how Bobby manages to keep the salmon firm enough to that deep depression with his thumb; it was all I could do to keep the patties together!  We set each one on an individual square of wax paper on the plate to make moving them into the pan easier when the time came.
- When recipes use a sauce to baste cooking meat and dip or drizzle later, I always separate the sauce into two bowls (one for basting and one for serving) to avoid contamination.
