The chopstick has just been updated to eco-friendly status. This version of the ancient utensil is made in Duluth, Minn., by Epicurean, known primarily for producing wood composite cutting boards. The chopsticks ($5.95) are repurposed from materials left behind when fashioning the boards. They’re wood fiber, in natural and slate color, won’t split, splinter, stain, or warp. For stir-frying, they’re heat resistant to 350 degrees and for cleanup, they’re dishwasher-safe. And here’s something you should know about all chopsticks: Using them makes you eat slower. They should be in every kitchen drawer.
