Instructions
Make the coffee mixture: In a small bowl, stir together the instant coffee and hot water until fully dissolved. Set aside to cool slightly.
6g (1 tbsp) instant coffee, 10g (1 tbsp) hot water
Cream the butter and sugars: In a mixing bowl, beat the softened butter with the icing sugar and granulated sugar for about 2–3 minutes until light and fluffy.
Add the egg and coffee: Mix in the egg, then pour in the cooled coffee mixture and blend until smooth. If the batter looks slightly curdled, don’t worry—the flour will bring it together.
50g (1 large egg) egg (weight is without shell)
Add the dry ingredients: Whisk together the flour, cornstarch, cinnamon, and salt. Add this to the bowl and mix on low speed until a soft, pipe-able dough forms.
140g (1 cup + 2 tbsp) all-purpose flour, 15g (2 tbsps) cornstarch, ½ tsp ground cinnamon, pinch of fine salt
Pipe and freeze the cookies: Transfer the dough to a piping bag fitted with a star tip (Wilton 1M, 2D, or 6B). Pipe rosettes or swirls onto a parchment-lined baking tray. Freeze the piped cookies for 10 minutes to help the ridges hold their shape.
Bake: Bake at 350°F (177°C) for 8 minutes, or until the tops look matte and the edges feel set. Cool completely on the tray before dipping.
Dip in chocolate: Once cooled, dip each cookie halfway into melted chocolate and place on parchment. While the chocolate is still wet, sprinkle with chopped pistachios. Let the chocolate firm up at room temperature, or chill for a few minutes to speed it up.
