Monday was Kenji Lopez-Alt's birthday! Since he's not a huge fan of sweets, we celebrated with duck liver mousse.

Unfortunately, all we had to eat with it was random cheese-filled cracker sandwiches we found in our cabinet.

Most exciting package this week: six pints of gelato and sorbetto from Capogiro in Philadelphia, one of our favorite gelato shops in the country (as mentioned in our book)! They sent us pistachio, Bacio, sea salt, pumpkin (made from Lancaster County neck pumpkin), Concord grape, and cactus pear. Yup, they all taste awesome. Thanks, Capogiro!

Best thing about receiving ice cream in the mail, aside from the ice cream: You get to play with dry ice!

Hambone stared at us from his doggy prison (aka, right by Kenji's desk) as we stuffed out faces with pastries. Sorry, Hambone!

Less exciting than gelato and French pastries: instant mashed potatoes and boxed stuffing. Yup, it's time for Thanksgiving taste tests.
Mashed potatoes, ready!

After seeing Christine's post about Goldenberg's Peanut Chews, Goldenberg sent us a whooooole lot of Peanut Chews (in updated packaging)! And we ate the heck out of 'em. Thanks, Goldenberg!
