2 (14 oz) cans sweetened condensed milk
3 wide-mouth 1/2-pint canning jars (or similar size that will fit in your slow cooker), sterilized
First make sure that your canning jars will fit in your slow cooker with 1" of head space above jars. Pour sweetened condensed milk into jars, put on lid and ring; finger tighten the rings. Place the jars into slow cooker. Add hot tap water, enough to cover the jar tops with 1" of water. Cook on low for 9-11 hours. Use tongs to remove a jar after 9 hours to see if color has caramelized and darkened enough; if not return to slow cooker until desired color is achieved. Use tongs to keep jars upright as you remove them from the slow cooker; rest on top of dish towel. Gently remove rings and wipe off water and any rust that may have formed on lid. Leave undisturbed until jars reach room temperature. Transfer to refrigerator. Keeps for at least 1 month. SERVING SUGGESTIONS: Stir into coffee or tea; spread on toast or muffins; gently heat in microwave and drizzle on ice cream, pancakes, or waffles; use it as a fruit dip (especially good with apples).
