This may not seem like a big deal to most of you Americans, but over here in Belgium (and I think a lot of European countries further up north) both were non-existent until a few weeks ago. We've had lemons, limes, oranges, grapefruit and mandarines since forever, but kumquats and now sweeties? It's a good day to be a Belgian citrus fan.
First thing I did when I got home with my newly bought organic citrus fruit was look up on the internet how to actually eat a kumquat. I had no idea! This video was pretty informative:

Just like the video suggested I kept chewing it so that the sweet rind would compensate the tartness of the juice. Tastes like more!
As for the sweetie, it tastes just like that, a sweet grapefruit. And I love it.
I for one welcome our new kumquat and sweetie overlords.
