For the dough, put honey, fat, brown sugar and salt in a saucepan and heat over medium heat while stirring until the sugar is dissolved and the ingredients have combined into a mass. Pour the mixture into a mixing bowl and let it cool down. Stir the egg into the honey mixture. Mix flour, cocoa, baking powder and gingerbread spice, sieve into the mixing bowl and knead into the honey mass with the dough hooks of the hand mixer. Wrap the dough in foil and refrigerate for at least 2 hours. Halve the dough.
Refrigerate one half. Roll out the second half on a floured work surface. Cut out hearts in different sizes (6-7 cm length). Place hearts on 1 baking tray lined with baking paper. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 8-10 minutes. Pull the pastry with the baking paper onto the cake rack and let it cool down. Process the remaining dough in the same way. Sift icing sugar. Place the egg whites, icing sugar and lemon juice in a tall mixing bowl and whip to a creamy glaze. Pour the icing into a freezer bag and cut off a small corner. Pour the icing onto the hearts as desired. Sprinkle with ground pistachios.
