  • After a while, lower the heat and let the mixture heat up till it reaches a temperature of at least 160 degrees Fahrenheit. If the mixture is too thick, you can dilute it by adding a little more water.
  • Let the mixture simmer for at least 2 hours and in between keep stirring the mixture so that the mixture does not end up burning.
