Instructions
In a large bowl, blend together the ground bison and the anticucho sauce. Hand-mash the ground bison until it becomes almost silky in texture.
Separate the meat mixture into 4 equal portions. Shape each portion into a patty 4 to 5 inches wide.
Prepare the grill for direct, medium-high-heat cooking. Baste the patties with anticucho sauce. Grill the burgers until they are nicely charred on the bottom, about 5 minutes. Flip the burgers, baste with more anticucho sauce, and grill until the burgers are medium, usually 5 minutes.
For the Anticucho Sauce
Whisk together all of the ingredients in a medium bowl. Cover and refrigerate the anticucho sauce overnight.
For the Ají Amarillo–Cumin Yogurt Sauce
Whisk together all of the ingredients in a medium bowl.
For the Final Assembly
Lightly toast the hamburger buns.
From the bottom bun, layer with sliced tomatoes, bison burger, sliced pickled cucumbers, ají amarillo–cumin yogurt sauce, and the top bun.
