Does it work the same for liquid and dry extract? seems like the malt would miss out on all the hoppy goodness of the boil.
does this work better with a specific style of beer or is it good across the board?
The hops need a bit more than just water to do their thing. You can add a little bit of the malt extract up front, or you can do what I do, go ahead and steep specialty grains first. Then, it's pretty much just like you said. Follow the recipe as if the malt had been added, then at the last 15-20 minutes, remove the pot from the heat, add your malt extract, make sure it's good and disolved, then put it back on the heat. Do not try adding the extract while it's still on the burner or the extract will dive to the bottom of the pot and scorch like crazy.
So far, I've only done it with an APA, a DIPA, and just last weekend with a Sam Adams Boston Stock clone, but I believe it would work great with most any style.
