I thought it would be complicated, but no. Boil water, dump the hamburger in, come back in two minutes. Yes, I said two minutes.
So this morning I get a pot out, get the water boiling, and start to crumble the hamburger into it. The little pieces immediately rose to the top already done. I threw the package away, washed my hands, returned to the pot, and wah la! A half-pound of hamburger browned to perfection. I drained it, rinsed it, and mixed it with the rice. Ellie loved it.
The article I read online said that it's a fast way to cook hamburger, but because you're taking all of the fat out of it, there isn't much taste left (which was true, I tasted it)...but for recipes calling for hamburger that will also have other spices or flavoring in it (tacos, for example), this works great! Also, if you have some frozen hamburger you can just dump the whole frozen piece of hamburger into the water. After a couple of minutes break it apart with a utensil and leave it to cook for a few more minutes. Soooo much faster than thawing it on the counter, in the fridge, or in the microwave and then frying it up.
Obviously boiling hamburger wouldn't work for every recipe, but I'm excited to "discover" this trick that I can use for some recipes or when I'm in a pinch for time!
