Dulce De Lecheby Mel's Kitchen Cafe
2 (14-ounces each) cans sweetened condensed milk
1-2 teaspoons pure vanilla extract or vanilla paste, optional
3 (1/2 pint each) canning jars with lids and rings
Open the cans of sweetened condensed milk and portion them equally into the three canning jars. Wipe the tops and sides of the canning jars, if needed, in case any of the sweetened condensed milk spilled down the sides. Place a lid and ring on the canning jar and screw tightly to seal. Put the three canning jars in a slow cooker and cover with water by one inch. It doesn’t matter whether the jars are laying on their side or standing up straight – do what works best for the size of slow cooker you have. Place the lid on the slow cooker and set to low for 8-9 hours, until the dulce de leche is deep golden brown. Carefully remove the jars from the hot water and let them cool. If desired, open the jars and stir in 1/2 – 1 teaspoon vanilla extract into each jar. Replace the lids and rings and store in the refrigerator.
