1can of sweetened condensed milknot a pull-tab can, or as many cans as you want, label removed
Instructions
Remove the label from the can(s).
Fill a large pot with enough water to cover the cans, laid sideways, by a few inches.
Bring the pot of water to a boil, then slightly cover and simmer for 2 hours for a light brown dulce de leche. Side Note: Keep an eye on the water throughout the cooking time to ensure the cans remain completely submerged by a few inches of water.
Simmer for 3 hours for a darker brown dulce de leche. Side Note: I cooked mine for 3 hours.
Remove from the water and place on a towel to cool for an hour before opening. Side Note: Do not attempt to open can while hot; this can cause pressurized hot dulce de leche to spray dangerously.
Transfer the cooled dulce de leche to an airtight jar or container and refrigerate for up to 3 weeks. Enjoy.
