Melt the dark chocolate au bain-marie. You do this by putting a heat-resistant bowl on a pan with a little water. Place the chocolate in the bowl and let it melt while stirring. Stir carefully, because you do not want any water getting into the chocolate.
When the chocolate has melted completely add the Arbol chilli flakes, cinnamon and sea salt and stir well.
Fill the chocolate letter form with the melted chocolate and smooth it out well. Place the mould in the fridge for at least 1 to 2 hours. As soon as the chocolate has completely hardened, you can carefully remove the letter from the mould by tapping it against the countertop. The letter should come loose by itself.
Fill the chocolate letter with your favourite dried pepper. For a super spicy chocolate letter use ground dried Naga Jolokia or make a white chocolate letter with Madame Jeanette Flakes.
You can also add nuts or dried fruit for extra variation!
