Milan 2013: patterned rolling pins that make edible plates and a meat grinder that squeezes out biodegradable bowls are among a set of kitchen products on show at Ventura Lambrate in Milan this week (+ slideshow + movies).

Altered Appliances is a collection of four projects by students from Rotterdam’s Piet Zwart Institute, all of which introduce low-tech, hand-powered appliances and ideas to the kitchen.
