mailing food to friends and family (domestically)
Occasionally I want to share something I've baked with my friends or family--and I can't because they live in different cities. It's usually on a whim, so I don't have a package ready to go and I'd have to wait a day to get to the post office. I'm thinking yeast breads, quick breads, cookies, nothing especially fancy but definitely could go stale, crumble to nothingness, get smashed, etc. Anybody send edible love and have recommendations for shipping containers to preserve freshness and structural integrity and reasonably-priced carriers (my two main destinations are same-state and next-state-over)? Should I freeze as soon as the item has cooled off and I decide I want to send it, until I can pack and post it?
