Sure you could snack on a sugary sweet pastry and walk around Essex Market, but why not get a bunch of fried rice balls filled with mozzarella and peas, pasta and cheese, or even Nutella? That’s exactly what you can do at Arancini Bros, who sell and package their rice balls in egg cartons. Structurally-innovative packaging aside, a half dozen cost $12 and make a great appetizer as you walk around the market looking for what else to eat.
