Echlin also makes the argument that eating with your fingers can be a bonding experience. As she says, "It's hard to stand on ceremony with people once you've all been sitting around eating with your fingers."
Our opinion? We're not entirely convinced.
We think that there's definitely a time and a place for eating with your hands. There are certain foods that we can all agree can be eaten with your hands no matter the context. Hamburgers, whole-cooked lobsters, and curry scooped with naan come to mind.
It also depends on context. If we're at home with a group of close friends, we don't have a problem with anyone using their fingers to nibble on green beans or snag the last sushi roll. But when we're at restaurants, we'll generally stick with whatever utensils the restaurant provides unless eating with your hands is clearly a part of the meal we've ordered.
What do you think? Are there foods that you will - or will not - eat with your fingers?
