Koji Fried Chicken

Ingredients

3½ pounds bone-in chicken pieces (split breasts cut in half, drumsticks, and/or thighs), trimmed7 tablespoons shio koji ½ cup plus 2 tablespoons (3.75 ounces/106 grams) firm granular rice koji ½ cup plus ⅓ cup (4 ounces/113 grams) all-purpose flour 1 cup (4 ounces/113 grams) cornstarch 2 teaspoons plus 1 teaspoon kosher salt, divided, plus extra for seasoning1 teaspoon plus one teaspoon pepper, divided1 teaspoon baking powder 1 cup buttermilk 6 cups vegetable oil for frying

Before You Begin

This recipe gets better with age. The longer you marinate the chicken (up to three days), the better and meatier it gets. And the longer you let the dredge sit on the chicken (up to 24 hours), the better and crispier the crust becomes. We use a fry-and-then-bake method for this chicken to prevent the sugar-rich rice koji in the coating from burning. There are a few options for buying rice koji. Japanese markets and some well-stocked high-end supermarkets carry it, but online is another good option (such as here). Click here for our shio koji recipe.

Instructions

  1. Combine chicken and shio koji in 1-gallon zipper-lock bag. Press out excess air, seal, and massage bag to evenly distribute shio koji. Refrigerate chicken for at least 8 hours or up to 3 days.
  2. Combine koji, flour, cornstarch, 2 teaspoons salt, 1 teaspoon pepper, and baking powder in blender and blend on high speed until finely ground, about 2 minutes. Transfer koji mixture to large shallow dish. Whisk buttermilk, remaining 1 teaspoon salt, and remaining 1 teaspoon pepper in large bowl. Working with 3 pieces at a time, dunk chicken in buttermilk mixture, then dredge in flour mixture, pressing mixture onto chicken to form thick, even coating. Place chicken, skin side up, on wire rack set in rimmed baking sheet. Refrigerate, uncovered, for at least 1½ hours or up to 24 hours.
  3. Adjust oven rack to middle position and heat oven to 350 degrees F/180 degrees C. Meanwhile, heat oil in large Dutch oven to 375 degrees F/190 degrees C over medium-high heat. Place half of chicken in oil, reduce heat to medium, and fry until first side is deep golden brown, 2 to 3 minutes. Flip chicken and continue to fry until second side is deep golden brown, 2 to 3 minutes longer. (Adjust heat as necessary to maintain oil temperature around 300 degrees F/149 degrees C.) Transfer chicken to second wire rack set in second rimmed baking sheet. Return oil to 375 degrees F/190 degrees C and repeat with remaining chicken.
  4. Bake chicken until breasts register 160 degrees F/71 degrees C and thighs/drumsticks register 170 degrees F/77 degrees C, 10 to 20 minutes, transferring pieces to serving platter as they come to temperature. Season chicken with salt to taste, and serve.

Why This Recipe Works

We think fried chicken is something that few people dislike (and if you hate it, we don’t want to know you anyway). Even when it’s bad, it’s still pretty good. Out in Cleveland, koji master Jeremy Umansky is working on a game-changing koji-cultured fried chicken that uses the mold as a crust. We also wanted to take advantage of the amazing tenderizing and flavor-boosting properties of shio koji, a mixture of rice koji, water, and salt. So we marinated a bunch of chicken in the stuff and even incorporated some dried granular rice koji into the coating itself to produce juicy, meaty, deep golden-brown, crunch-tastic chicken.
