You know what a crawfish is, right? That's a lobster after taxes.
+7 points for CallmeQ for making the distinction between sushi and sashimi, which are NOT the same thing. Around west TN where I live if you say "sushi" you immediately get a reply of "eeww, raw fish!"
Most of my gastronomic experiments have been the result of frequenting the salvage grocery. Never know what you'll find there. I don't go to save money, I go to find neat stuff I will never find at the regular supermarket.
Did you know the cashew is actually a fruit with a drupe on the end? The drupe is what they roast, salt, pack and sell to the USA. The fruit is rather sour. I found this out when I got curious about a jar of cashew juice I saw at the salvage grocery.
Did you know in Britain they have a candy bar called the Ritter Sport Bar? It is specifically shaped to be easily fit in the pocket of a sport jacket. And their dark chocolate bar with whole hazelnuts is delicious!
There's a company I wish I could buy out and own. It is called the Wicked Good company. They make things you wouldn't normally think of making, but they are delicious - like caramel/mustard sauce. Never would have thought of combining those, but the result was... well... wicked good!
Getting away from the salvage grocery: I recently got interested in goat cheese, as I am allergic to the kind from cows. I found there is a whole universe of goat cheeses. The semi-soft, acerbic chevre is what most people think of as goat cheese, but the double creme brie was much better. In fact goat brie tasted better to me than the cow brie you get in most stores. I also found a goat cheese that tastes just like parmesan. Then there's the Drunken Goat Cheese, a soft cheese bathed in wine. I swear I was not drunk and it was still delicious.
