It is quite fast for making dulce de leche, but more involved than the electric pressure cooker method
- Get a standard size wide mouth mason jar
- Pour half a can of sweetened condensed milk into the jar (this technique is for small batches, but dulce de leche is *extremely* rich, so this is several servings)
- Microwave for about a minute, make sure that the dulce de leche doesn't boil over, it probably won't yet but it depends on your microwave power
- Now start microwaving by hitting the 30 seconds / start button repeatedly and watching the sweetened condensed milk LIKE A HAWK. It will eventually boil up almost to the top of the jar and PRESS STOP before it makes a huge mess
- Pull it out, mix it with a fork
- Put it back in, keep starting the microwave, stopping right before it hits the top, wait for it to settle, start it up again, every third time pull it out and whisk it
- When it's a nice golden brown you're good
