Miso Walnut Chocolate Chip Cookies

Adapted from SIFT by Nicola Lamb
When you form the five mounds of dough, avoid compacting them too tight. You want to form them into loose balls rather than rolling them in your hands into smooth rounds. They're best when you chop the chocolate from bars of good-quality dark chocolate, and I leave the pieces fairly large - about the size of almonds, but you can use store-bought chocolate chunks if you wish.
I baked my batch of cookies for 15 to 16 minutes, although the original recipe says 18 minutes. All ovens are different, but they're done when they're light brown across the top. The cookies shown in the post were baked on a cloudy day, so may look a bit dark. You want to err on the side of underbaking rather than over baking. Another tip is that you can sprinkle extra flaky salt on top of each cookie when they come out the oven.
These cookies are best enjoyed the day they’re made but are delicious the next day as well. Store them in an air-tight container at room temperature.

Miso walnuts

  • 3 tablespoons mirin rice wine
  • 3 tablespoons granulated sugar
  • 3 tablespoons (50g) white miso
  • 1 cup (100g) walnut halves, toasted

Cookie dough

  • 6 tablespoons (90g) unsalted butter, at room temperature
  • 6 tablespoons (85g) light brown sugar
  • 6 tablespoons (85g) granulated sugar
  • 1 large egg, at room temperature
  • 1 3/4 cups (220g) all-purpose flour
  • 1/2 teaspoon baking soda
  • 1 1/4 teaspoon flaky sea salt, or 1 teaspoon Diamond Crystal kosher salt
  • 9 ounces (255g) bittersweet or semisweet chocolate, chopped in large chunks
  • To make the miso walnuts, in a medium saucepan or skillet over moderate heat, warm the mirin, the granulated sugar, and the miso, stirring to incorporate and smooth out the ingredients. When the mixture starts to boil, add the walnuts and cook, stirring frequently, until the walnuts are completely coated and the miso mixture has almost all been absorbed by the walnuts, which will take a couple of minutes. They're done when there's only about a tablespoon of the miso syrup in the pan. Remove from heat and let cool, giving them a stir a few times as they cool.
  • To make the cookies, preheat the oven to 375ºF (190ºC). Line a baking sheet with parchment paper.
  • In the bowl of a stand mixer fitted with the paddle attachment on low speed, or by hand, cream the butter and sugars until well-incorporated for about 1 minute. Do not beat the mixture until it's too light or overly fluffy, which can cause the cookies to spread too much during baking.
  • Mix in the egg. Sift the flour and baking soda together in a small bowl then mix that into the dough along with the salt.
  • Break or cut the walnuts up a little, but not too much, and stir them into the dough, then stir in the chunks of chocolate. You may need to get your hands in there to get everything thoroughly combined, but don't overmix. The dough can be somewhat irregular.
  • Shape the dough into 5 equal mounds on the baking sheet, each about 6 ounces (180g), placing them evenly spaced apart. Bake the cookies for 15-18 minutes, sprinkling them with additional flaky sea salt after they come out of the oven, if you wish. The cookies are done when they are light golden brown across the tip. Err on the side of underbaking rather than overbaking.

Notes

Mirin is a sweet rice wine, available in Asian markets and well-stocked supermarkets. There are some substitutes for mirin here.
