You may convert evaporated milk into condensed milk by adding sugar to it. For each cup of evaporated milk add about 1 and 1/4 cups of sugar. Pour the mixture in a pan, stir while heating on the stovetop until the sugar completely dissolves. Let cool. Is this for real, isn't condensed milk kind of thick. My problem is canned has to much sugar so i would like to use My own whey low sugar.
