So I love cooked sweetened condensed milk (caramel, dulce de leche, all that). It's really simple to make - just cook the stuff for a while - and it tastes awesome. That said, I could really stand it being a little less sweet (not a carb thing, just a taste thing). So I was wondering - can I use evaporated milk to make something similar? And if not, is there a way to make cooked condensed milk with a bit less sugar?
Milk contains lactose naturally, so there will always be a minimum amount of sugar that any condensed milk will contain.
Having said the above, the recipe for making lowest-possible-sugar condensed milk, is evaporated milk (which still contains all of the lactose), so that's still sweet as well, but not overpoweringly so like condensed milk.
If evaporated milk is not sweet enough to your taste, keep adding vanilla sugar to it while heating gently and tasting frequently till it reaches the exact taste you want!
Actually, condensed milk and evaporated milk are synonyms semantically. What you're really talking about is "condensed sweetened milk" ;-)
Condensed milk can have up to 40% more sugar in it than regular evaporated milk. I just made this recipe--an hour ago--using condensed milk (it was all I had). Then I cut out one cup of white sugar. It looks fine now that I'm done, but it took a long time to cook and the flavor is a little bland. I think it needed more sugar in it to properly carmelize. While the condensed milk was sweetened with some kind of sugar, it wasn't the right kind. I need to learn a lot more about the science and chemistry of sugar.
