The easy way to make Dulce De Leche is to put an unopened can of sweetened
condensed milk into a small pan. Add water to bring it to about 3/4 the way
up the can.

That's an easy way to make an explosion.

Add water to completely cover the can AT ALL TIMES by at least 2". Do
not answer the phone while this is going on. Do not answer the door.
Do not pass go, do not collect $200.

Making this is safe, but it does need to be watched, do not allow the
can to 'surface' in the water at any time.
