Matcha Shortbread with Yuzu White Chocolate Glaze

December again, and the city has put on its lights. The tree at Pioneer Square is up. The shops are decorated. The rain has turned to a cold, persistent drizzle that makes the Christmas lights reflect in the puddles, so the whole city is doubled — the light above and the light below, the real and the reflection, which is how I experience most things: the event and the echo, the happening and the feeling about the happening, never just one layer, always two.

I started the osechi preparations early this year — the kuromame are soaking, the datemaki eggs are planned, and I ordered kazunoko (herring roe) from Uwajimaya, which required a special order and a conversation with the fishmonger that involved me saying "kazunoko" three times and him saying "what?" three times until a Japanese employee overheard and translated. The challenges of cooking ancestral food in a city where your ancestors did not live: the ingredients do not know they are expected.

I made matcha shortbread again — my Christmas tradition now, the green cookie that bridges December and January, Christmas and New Year's, Brian's holiday and mine. This year I added a yuzu glaze — white chocolate thinned with yuzu juice, drizzled over the cooled cookies. The green and white combination looked like a winter garden. I brought them to Brian's office party and they disappeared and Brian said, proudly, "My wife made those," and the pride in his voice was real and uncomplicated and I held onto it like a coin found on the sidewalk — small, unexpected, worth keeping.

Miya is obsessed with Christmas lights. She points at every house, every tree, every strand of lights and says "pretty" with the wide-eyed reverence of someone experiencing beauty for the first time. Her wonder refreshes mine. I had forgotten that lights could be amazing. I had forgotten that the world could surprise me. Miya reminds me every day that surprise is possible, that wonder is not a childhood condition but a choice, and that the choice to find something pretty is available to everyone, even anxious thirty-two-year-olds in the rain.

Every year I mean to write this recipe down properly, and every year the cookies are gone before I get the chance — eaten, gifted, or packed into tins before I’ve measured anything twice. This year I paid attention. The yuzu glaze was the new addition, and it was the right one: the sharp, floral citrus against the grassy matcha made the whole cookie feel like it had a second layer, the way the Christmas lights doubled in the puddles outside. If you can find yuzu juice — Uwajimaya carries it bottled, or check a Japanese grocery — use it. It is worth the trip.

Prep Time: 20 min | Chill Time: 30 min | Cook Time: 14 min | Total Time: 1 hr 10 min | Servings: 24 cookies

Ingredients

2 cups all-purpose flour
2 tablespoons matcha powder (ceremonial or culinary grade)
1/4 teaspoon fine sea salt
1 cup (2 sticks) unsalted butter, softened to room temperature
1/2 cup powdered sugar, sifted
1 teaspoon pure vanilla extract
For the yuzu glaze: 4 oz white chocolate, finely chopped
2 tablespoons yuzu juice (fresh or bottled)
1 tablespoon heavy cream
Pinch of flaky sea salt, for finishing

Instructions

Mix dry ingredients. Whisk together the flour, matcha powder, and fine sea salt in a medium bowl until the matcha is evenly distributed with no streaks. Set aside.
Cream butter and sugar. In a large bowl, beat the softened butter and powdered sugar with a hand mixer or stand mixer on medium speed until light and fluffy, about 3 minutes. Add the vanilla extract and beat 30 seconds more.
Form the dough. Add the flour mixture to the butter mixture and mix on low speed until just combined — the dough will look crumbly at first but will come together. Do not overmix.
Shape and chill. Turn the dough out onto a sheet of plastic wrap and press it into a log approximately 2 inches in diameter. Wrap tightly and refrigerate for at least 30 minutes, or up to 3 days.
Preheat the oven. When ready to bake, preheat oven to 325°F. Line two baking sheets with parchment paper.
Slice and arrange. Remove the dough log from the refrigerator and slice into rounds 1/4 inch thick. Place on prepared baking sheets, spacing about 1 inch apart. The dough will not spread much.
Bake. Bake 12 to 14 minutes, until the edges are just set and the bottoms are very lightly golden. The tops will still look pale — that is correct. Do not overbake; shortbread firms as it cools. Let cookies rest on the pan for 5 minutes, then transfer to a wire rack to cool completely before glazing.
Make the yuzu glaze. Combine the chopped white chocolate and heavy cream in a microwave-safe bowl. Microwave in 20-second increments, stirring between each, until the chocolate is fully melted and smooth. Stir in the yuzu juice. If the glaze seizes slightly, add cream 1 teaspoon at a time and stir until smooth. Allow to cool 5 to 8 minutes, until it thickens to a drizzleable consistency.
Glaze and finish. Using a spoon or a small piping bag, drizzle the yuzu glaze over the completely cooled cookies in thin lines. Finish with a small pinch of flaky sea salt over each cookie while the glaze is still wet. Allow the glaze to set at room temperature for 20 to 30 minutes before storing or stacking.
