CHOCOLATE CHIP COOKIES WITH BLACK SESAME AND SEAWEED

Steps:

• In a medium bowl, whisk together the all-purpose and rye flours, baking powder, baking soda and sea salt; set aside.
• In a stand mixer fitted with the paddle attachment, beat both sugars together on medium speed to blend. Add butter and beat on medium until beginning to lighten and starting to become creamy, about 2 minutes.
• Add the eggs and egg yolk one at a time to the butter mixture, beating until incorporated, then add the black sesame paste and vanilla, and blend just until combined.
• Add the flour mixture all at once, and use a sturdy rubber spatula to fold it into the butter mixture until about halfway combined, and the mixture goes from a shaggy mess to a semi-combined dough. Scatter the chocolate and seaweed on top and fold just until dough forms. (A gentle touch is necessary, as overmixing can cause the dough to separate and crumble.)
• Add the black sesame seeds to a shallow bowl. Using a 1/4 cup measuring cup, portion the dough into about 22 balls (60 grams each). Working with one portion of dough at a time, roll it between your palms until rounded, then gently roll it into the sesame seeds until coated all over. Arrange on a parchment-lined baking sheet and transfer to the refrigerator to chill at least 4 hours. (You can prepare the dough balls up to one week in advance; transfer to a lidded container or loosely cover them with plastic wrap and refrigerate.)
• When ready to bake, heat the oven to 400 degrees. Arrange the cookies a few inches apart on a large baking sheet and bake until they have spread out slightly but are still puffed in the center, about 12 minutes. Once you've removed the baking sheet from the oven, gently tap the center of each cookie down using the bottom of a ladle, pressing just until you've created a slightly indented crater. (This technique helps ensure a gooey and chewy center.)
• Allow the cookies to cool for 10 minutes before transferring to a wire rack to cool completely. Store, covered, at room temperature, up to 2 days.
