It is a delicious carmel spread from Brazil. I got this from a friend who was an exchange student there, it is the most addicting thing ever, watch out, this is NOT low in fat...quite the contrary :)but soooo worth it.
- 1 can sweetened condensed milk
- Pierce the top of the can with a bottle opener and remove paper from can.
- Cover top of can tightly with aluminum foil.
- Place in a sauce pan, submerge in water to 1" from the top.
- Boil over med-low heat for 4 hours.
- Open lid of can and place contents in a bowl.
- EXCELLENT for dipping apples, pears, crackers and for spreading of bread and great on ice cream!
Actually, the people that boil the can without opening it first are not idiots but know what they are doing. If you submerge the whole can in water (at least an inch of water above the can) the can will never explode. Instead, you will be able to make the caramel in half the time, since it will be boiled under pressure. In two hours you will have semi-solid spread and in 3.5 a solid dessert. Plus it's easy, no need to open the can, find a foil, measure the water level. Just take the can and boil it. Voila.
You're right, this is an incredible sauce! I can remember doing this in college in the '70's, so it has been around awhile (ooo...I'm getting old!). At that time, warnings were abundant, regarding exploding cans, burns, etc. But I think the method you describe can be done safely. I think the previous idiots were trying to boil the can without opening it first (DUH!).
Previously I used to cook this (can unopened method) a lot, but as I like to see what I'm cooking, today I tried yet another method: pour contents of can into a sterile glass jar, the kind you would use for fruit or jam preserves. Close lid with ring in place. Put in a pot with water level an inch or so higher than contents of jar. Boil until desired shade of golden brown. It worked!! I think I boiled it for approx. 1 1/2 hours.
