Mexican Cafe de Olla

Heat the water, sugar and cinnamon in a medium saucepan, stirring frequently. Bring the mixture to a boil making sure to stir until the sugar is dissolved. Continue to boil for 20 minutes until the mixture is reduced by a quarter. Add the ground coffee and stir until the mixture returns to a boil. Remove the pan from the heat, cover and allow to stand for at least five minutes. Strain the mixture using a fine sieve or a double layer of cheesecloth. Pour into mugs and server while hot. Top with a few aniseeds if you like.
