Thanks everyone who posted -- there were a lot of great dessert suggestions, and I have the sneaky suspicion that I will be eating my way through the comments list for quite some time!
The winner was lucky comment number 19! That means you, Janssen!
Also, congratulations to Caitlin who won second place. I didn't originally have a second place but I went out and looked at the lemon tree and I have what by all appearances is several hundred lemons still left and it's physically impossible for me to just throw them away, so, Caitlin will be receiving a small USPS flat rate box.
