Yogurt

In the Boston, MA area, yogurt that I like are hard to find. I finally picked the Fage yogurt that I find great for cooking and even eating like a normal yogurt. Can be found at Whole Foods

Whole foods market

Whole foods market is the easiest place in Cambridge, MA, to find the food ingredients you need. They even have a blog to share their philosophy, locally grown products, supporting local farmers, etc...
