Can evaporated milk be converted to sweetened condensed?
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.  The heating of evaporated milk is similar to the treatment condensed milk undergoes, so the evaporated milk with sugar should be a perfect replacement.
