REI has a mug that's great for broths too - can't do anything thick though: http://www.rei.com/product/799295

Like yours, it keeps things amazingly hot for hours. I've been shocked that my tea is still piping hot four or five hours later. It's amazing!

I'm trying to plan for a 24-hour road race and think about what foods to bring/eat. It's a lapped race, so I'll be by the pitstops all night long. Just can't think about what I might want to eat (can't stop to eat - has to be eaten on the bike) and I draw a blank beyond Pringles, peanut-butter crackers and Trader Joe's Flattened Bananas.
