Homemade dulce de leche will last up to a month if stored in the refrigerator. We recommend keeping it in a jar with a tight-sealing lid. If you do not store it in a jar, be sure to put plastic wrap on the surface to prevent a skin from forming.
Ingredients
-
2 (14-ounce) cans sweetened condensed milk
Description
Cook condensed milk in double boiler:
Empty milk into the top of a double boiler or a heatproof bowl over a pan of simmering water. Cover with a tight-fitting lid. Cook, stirring every 10 to 15 minutes, until milk is thick and amber in color, about 5 hours.
Remove from heat and beat with a wooden spoon to smooth out.
Transfer to a clean bowl or jar, and refrigerate.
