In Denmark we don't have condensed milk in our regular stores and I've actually only seen it in an UK-import store a few years ago. Is there an alternative to it or can you craft it with regular cooking equipment? 
To make sweetened condensed milk:     The best make-your-own version is to   mix 1 cup of evaporated milk with   1-1/4 cups of sugar in a saucepan,   heat and stir until the sugar is   completely dissolved, and let cool.      If you don't have evaporated milk on   hand either, you can make your own by   slowly simmering any quantity of milk   in a pan until it reduced by 60%, and   then adding the sugar.
