Step‑by‑Step Instructions for Shiroi Koibito
Step 1: Prepare the Cookie Dough
In a large mixing bowl, cream together ½ cup of unsalted butter and ½ cup powdered sugar until the mixture becomes pale and fluffy, about 3-5 minutes. Next, beat in one egg and one teaspoon of vanilla extract until well combined. The Shiroi Koibito dough should be smooth and creamy, ready for the next step.
Step 2: Mix Dry Ingredients
Gradually add 1 cup of all-purpose flour to the butter mixture, mixing until just combined. Be careful not to overmix, as you want the batter to stay light and airy. The dough should come together without any visible dry flour, forming a soft, pliable consistency ideal for piping.
Step 3: Pipe the Cookies
Transfer the cookie dough into a piping bag fitted with a round or star tip. On a baking sheet lined with parchment paper, pipe your desired shapes—traditionally long and thin for Shiroi Koibito. Leave some space between each cookie, as they will spread slightly during baking. Aim for uniformity to achieve that beautiful presentation.
Step 4: Bake the Cookies
Preheat your oven to 350°F (175°C). Once heated, place your baking sheet in the oven and bake for 15-20 minutes, or until the edges of the cookies turn lightly golden. Keep an eye on them to ensure they don’t overbake. The cookies should remain soft yet hold their shape, perfect for sandwiching.
Step 5: Cool the Cookies
After baking, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes. This cooling period helps firm them up slightly. Then, transfer the cookies to a wire rack to cool completely, which is crucial before adding the white chocolate filling.
Step 6: Assemble Shiroi Koibito
Once cooled, melt 6 ounces of white chocolate in a microwave or over a double boiler until smooth. Sandwhich two cookies together with a generous amount of melted white chocolate, ensuring the filling oozes slightly out of the edges for a delightful look. Let the assembled cookies set at room temperature for about 30 minutes.
