1 cup hot tap water 2 cups sugar 2 cups instant non-fat dry milk powder 6 Tbsp melted margarine Blender or electric beaters First get out your blender. You can beat the mixture with electric beaters if you prefer, but a blender really does a better job. Measure your hot water into the blender. Add the sugar, dry milk powder and melted margarine. Put the lid on the blender and whirl it around for a full minute. The mixture will be kind of thin, but will thicken up after standing for about an hour. This recipe makes about 3 cups or the equivalent of two cans of condensed milk. Each store-bought can of sweetened condensed milk contains about 1 ½ cups. The mixture may be measured and used right away in any recipe calling for sweetened condensed milk or for longer storage, divide the mixture equally between two clean pint size canning jars. Store them in the fridge for a week. For longer storage freeze them for a few months and then just thaw before using. Click here to purchase
