I have heard about DDL Dulce de leche ( you can learn more from here) long time ago but I can't try as it was not easy to obtain full cream condensed milk last time. Anyway, after I received the F&N full cream sweetened condensed milk , i immediately try to make DDL at home.
There are few ways to make DDL at home, you can refer here for more. As for me, i tried the simplest way, place the can in a deep pot that fill with water and put a rag under the can. Bring water to boil, once water boiled, lower the heat and simmer for 3-4hrs (do not close with lid as when you close with lid, water tend to boil).
Once done, carefully bring the can out and place it in tap water. When the can has cooled down ( tap water became warm), open the can and enjoy with spread DDL on bread or biscuits, or use it to make cake or frosting a cake and etc.
For me, it still taste like condensed milk but with a hint of caramel aroma.
