We Americans eat differently than the Brits. And, after living here for 3 years, I'm starting to come around to the way the Brits do it more & more often (hence the friends' comments). What do I mean, you ask? Simples.
Americans, when faced with needing to use a knife with their meal, will put the knife in their right hand and fork in the left. We'll cut our food, and then switch hands and use the fork in the right hand to eat with. Back and forth and back and forth.
Not the Brits. Once the knife goes in the right hand, it stays there. And, even more interestingly is that unlike Americans who will use the fork in a scooping motion, the Brits don't flip the fork over; rather, they use the knife to scoot food onto the back of the fork tines and then eat.
After 3 years of being in London, I'm starting to notice that I'm adopting this style of eating too (hence the friends' comments when I was in the US). Not all the time, but half the time at least. It kinda makes sense: the back & forth kife/fork switching really is unnecessary.
Though, I can't help but wonder how the 'American-style' came to pass..
