Thank you so much for posting this safer version! I used the oven method and it turned out great.
I have always made this by boiling an unopened can for an hour, and it has worked fine. But I was happy to have another way to go, as I didnt like having my daughter in the room while boiling. The oven meathod worked great, but was a little drier than in the can (not much) I couldnt get the microwave method to work, but have a higher powed microwave than most, so that maybe why.
I found this site AFTER making it by boiling the can for 4 hours. No explosions, thank goodness! It turned out very yummy. However, it was tedious to watch for 4 hours, and the suggestion of possible explosion made me uncomfortable. Will try one of these methods next time.
this is Argentinean Dulce de Leche, almost impossible to buy outside Argentina except at great price!
