Melt the vegan butter, syrup and vanilla paste in a saucepan.
In a mixing bowl, combine the flour, ground almonds, spices, baking powder, bicarbonate of soda and salt.
Add the syrup mixture to the dry ingredients and mix until all the ingredients are just combined.
Cover the bowl with cling film and place in the fridge for 30 minutes.
Pre heat the oven to 180C/ 160C fan. Generously flour your hands and the work surface. Proceed to roll the dough out to roughly the thickness of a pound coin. Use a 7 cm cookie cutter to cut out 24 cookies.
Place the cookies on a parchment lined tray and bake in the oven for 12-14 minutes. Remove from the oven, the cookies should be light gold in colour and slightly soft to the touch. Allow to cool completely.
Melt the chocolate and smooth half over the cookie. You may find it useful to use a piece of foil or kitchen paper to keep the design neat. Crush the pistachios and sprinkle over the melted dark chocolate. Leave to cool.
