An organic-minded restaurateur opens a third outlet for her bubbling specialty. Xu Junqian reports from Shanghai.

Don't expect to order or dip common ingredients like corn or mini-carrots in the simmering Matsutake mushroom and chicken broth at this time of the year at Qimin Hotpot Marketplace.

Nor should you hope for the usual spice blast from any of its bubbling soups or dipping sauces; for one thing, the saltiness has been toned down by 60 percent of the typical seasoning.
