Tureen
My least favorite thing about serving soup is the presentation. After carefully preparing ingredients and tweaking seasonings to perfection, I hate just plopping the possibly less-than-attractive kettle on the table. The alternatives are to keep the kettle out of sight by serving from the kitchen (not always practical when soup is a main dish for a family who will likely want seconds), or use a soup tureen. A tureen is typically porcelain or stoneware and has a lid to keep things warm. You'll want to look for one that's a reasonable size for your needs and, since it involves transporting a gallon of boiling hot liquid, look for one with a very stable base and useful-looking handles. (TIPS AND TRICKS: About 10 minutes before using your tureen, fill it with boiling or very hot water and then pour it out just before filling with soup. The hot water will warm up your dish and that will keep your soup hotter when served.) A tureen will typically come with a matching ladle.
Storage
There's one more dish that I bought recently for someone who likes to take soup for lunch. This CorningWare mug has a lid that really fits well and seems to be leak-free. It's big enough for a generous serving and microwaves much better than the plastic bowl he was using. Hardly essential, but I do recommend the product. (I got it at Wal-Mart for less than the price listed on the Corning website.)
