Kuromitsu Recipe - The Delectable Hodgepodge

Mix and heat ingredients. Mix the ingredients in a small saucepan and bring to a boil over medium heat. Reduce heat to low and stir constantly until the sugar is completely dissolved. Simmer. Simmer gently for 5 to 10 minutes, until the liquid thickens slightly. Keep in mind the syrup will thicken further when cooled. Chill. Remove from heat and let cool, then transfer to the refrigerator to chill.
