Just curious as to what most people do. I've started boiling for 5 minutes, but I used to boil longer.

Exact same here. Used to boil longer and now I go for 5 minutes (had too much boil off and would end up with higher gravity and less starter than I wanted)

I boil 15 minutes in the ehrlenmeyer flask. I use a little fermcap and haven't noticed a big boil off. I do cover loosely with foil.

10 mins with the cover on. I figure DMS in a starter won't matter.
Who is this Rorschach guy? And why did he paint so many pictures of my parents fighting?

5 minutes here with no lid. I decant my starter before pitching anyway so the boil of the starter is just to sanitize and dissolve the DME.

DMS is a non issue in extract as it has already been taken care of in the manufacture of the extract

Uh, MAYBE 5 minutes. Really just a few minutes to sanitize the lid of the pot/pot itself with steam. I like to use just a scosche more water than I want for my starter and this way I don't boil off much/any.

for me it varies, but i've boiled for as little as 1 minute. the idea is to sterilize the wort and that happens in a few seconds at 212*F. the rest, to my mind, is to create steam to sterilize the pot/flask/etc you're boiling in. certainly nothing wrong with boiling for 15 minutes, but i can't think of any reason such a long boil is necessary. am i missing something?
