Dulce de leche recipe

400 g sweetened condensed milk

Pour the condensed milk into a small bowl. Place the bowl in a large pot. Fill pot with water to cover ¾ of the bowl and place over medium high heat. As soon as the water comes to a boil reduce to a simmer then just keep an occasional eye on the water level and refill as necessary. 2 hours of simmering will give you a light golden colour. Leaving it longer will result in a darker amber colour with a richer flavour. Leave to cool slightly and then transfer to a jar with a lid. Use within 1 month.
