How to make the cookie 1. Preheat the oven to 350 °F and line a baking sheet with baking paper. 2. In a mixing bowl, beat the softened butter and icing sugar until light and creamy. Add the egg whites and vanilla extract and continue to beat until smooth. 3. Gradually sift in the flour and a pinch of salt, mixing gently until just combined. The dough will be a little thick.
5. Bake for about 13-15 minutes, or until the edges are lightly golden brown. Keep an eye on them as they bake quickly. Once baked, allow the cookies to cool completely on a wire rack. How to make the white chocolate filling 1. Melt the white chocolate in a double boiler, then use the same mold as the biscuits. Pour chocolate into each hole of the mold and flatten with a scraper. You can lift the mould up immediately to form a square, or put it in the fridge immediately before removing. 2. don't forget to leave some white chocolate to stick the cookies to each other.
4. Transfer the dough to an icing or piping bag (with the tip cut off) and pipe into the Shiroi Koibito molds, filling each section with the dough. Use a scraper to flatten the dough, then lift the mold. The cookies will be square and very thin.
Assemble the Shiroi Koibito 1. Prepare two cookies. Spread a little of the melted white chocolate in the center, cover with the white chocolate from the fridge, then cover with the second cookie to make a sandwich. 2. Leave the cookies to set for a few minutes or put them in the fridge for a quicker result. The white chocolate will harden and bind the biscuits together. 3. Enjoy your homemade Shiroi Koibito!
