As I gather, there are various methods of making Dulce de leche from a can of sweetened condensed milk. I've actually tried boiling the can for 3-4 hours twice, and the results not entirely to my satisfaction. I don't get the caramelized dark color. As I opened the can, and the color was lighter than expected, I did let the can boil for another hour but no significant changes in color was observed! Today I was googling to find out more about this method, I get familiar with another method which is to make Delce de leche in the oven. So what I want to know is, is it possible to put the undone dulce de leche I made in the pot two days ago in the oven to finally achieve the desired caramelized and dark color?
This question is quite informative, but not very helpful solution-wise.
