'TIS THE SEASON: CITRUS

If you live anywhere in southernmost Texas or the south-coastal U.S., now is the time when fresh citrus abounds.  We don't, but we happen to have a really nice contractor that we've enjoyed working with on several remodel/repair projects.  He showed up on our porch out of the blue the other day, with a bushel basket in his arms.  Guess what was in it?  This!

Lemons and oranges and limes, oh my!  Not to mention all the grapefruit, and three avocados (one of which was served as "avocado vinaigrette" with our dinner last night).  With just the two of us here, I'm not so sure we can eat our way through all of this before it starts to go bad.  So I was wondering, anybody got some great recipes or ideas for using any of this, other than the following one?
