Best Duck Fat Seared Beef Burger with Garlic Fennel Confit and Dijon Herb mayonaise

Ingredients 

1 large fatty duck breast (fat for rendering and 7oz. meat, quartered, for burgers)
1 & 1/3 cup very thinly sliced fennel bulb, plus 2 tablespoons chopped frond
2 & 1/2 teaspoons kosher salt, divided
1 & 1/8 teaspoon fresh ground black pepper
28 medium cloves peeled garlic, root end trimmed
1 cup light olive oil
1/3 cup plus 1 tablespoon fig preserves
2 tablespoons, plus 1 teaspoon Dijon mustard, divided
1 & 1/3 cup soft fresh potato or white bread, torn into bits
6 tablespoons whole milk
3/4 cup quality prepared mayonnaise
30oz. fresh skirt steak, cut in 6 pieces
5 juniper berries, ground
8oz. cow’s milk Blue cheese such as Sweetgrass Dairy Asher Blue, 6 slices/portions
6 rich buttery type bakery Buns, sesame seeded if possible, split
2 cups of young Arugula leaves

Instructions 

Remove duck fat from breast, score fat with sharp knife and place in large iron skillet over medium
heat on grill. Cook, turning occasionally, until you have about 8 tablespoons rendered fat, about 25 minutes. Leaving 1 tablespoon fat in pan, sauté sliced fennel with 1/4 teaspoon salt, and 1/8 teaspoon black pepper, over medium flame for 6-8 minutes until beginning to caramelize. Remove from heat, stir in garlic. Cool slightly, spoon into a small heatproof saucepan with olive oil, (don’t clean skillet). Cook over very low heat for 40 minutes or until garlic is very soft. Small bubbles will rise, but do not "boil" the oil. Cool confit until oil is room temperature. Strain out garlic and fennel, save the flavored oil for another use (use to supplement duck fat if not enough renders). In a small bowl, mash confit into a chunky "confiture" and set aside.

Meanwhile for sauce, in small bowl, mix preserves with 2 tablespoons mustard, set aside. In small bowl, moisten bread with milk and set aside. In a small bowl, mix mayonnaise with 1 teaspoon mustard and the chopped fennel frond, chill.

For burgers, in clean processor bowl, pulse duck breast meat until coarsely ground, remove to large bowl. Do the same with the beef in 2 portions. Pick any large strings of tough fat from beef. Add all beef and duck back to processor with 5 tablespoons of rendered duck fat, pulse until just combined and meat is more finely ground. Return to bowl and with fork, gently stir in soaked bread, juniper, remaining 2 & 1/4 teaspoons salt and teaspoon pepper. Form into 6 equal patties to fit buns, with a dimple pressed into center of each for more even cooking.
Return the large skillet to grate over high heat until very hot. Add a tablespoon of duck fat, Sear 3 burgers at the time quickly on each side, then transfer to grill grate to finish. Add last tablespoon of the duck fat for second batch of patties. Grill until medium, or desired doneness, 3-4 minutes per side, basting with fig sauce. Remove, add cheese, cover loosely to keep warm.

Toast buns over medium heat until golden. Spread tops with confiture, and bottoms with mayonnaise, topped with lettuce, then burgers and top bun. Serves 6.

Comments 

Over here my big beefy burger larded with duck fat. Yes, in ways you are simple, but sometimes it’s the little things. Your duck fat sear, ummmm, and homemade mayo, ohhhh. I bet you got your hard-to-find-words-for garlic and fennel confit from your mother. All dressed up with a fig mop and finished with a cow’s milk blue. Somehow rich, classic, amazing and restrained, all at once. The good ones are always eaten! Do try to find Sweetgrass dairy’s Asher Blue, made just a fig’s throw from me, in south Georgia.
