Technique of the Week: Halving Cherry Tomatoes and Grapes

Okay, this might sound kind of stupid.  Do I really need to be telling you how to cut cherry tomatoes or grapes in half?  No.  But.  If you've ever been faced with cutting a carton of tiny tomatoes in half for a Greek salad, you know how long it takes and how tedious it is.  Ugh.  And if you have small children, there is no getting around cutting loads of grapes in half.  Save yourself some time and effort and use my super-slick way to halve cherry tomatoes and grapes.

Wash your round fruits and place them on an upside-down plate.  You want one with a ridge around the bottom, preferably just big enough to contain all the fruit.
  

Top with a matching plate.  Ideally, you're using lightweight plates so as not to squish the fruit.

Place one hand on top of the plate stack and use the other hand to slice between the plates with a long serrated knife (like a bread knife).  And that's it, round things perfectly sliced in half in about 30 seconds.

Okay, now your turn.  What's your favorite kitchen trick?
