Okay, so cutting grapes in half is not a difficult culinary trick, but when you have a recipe that calls for two cups of halved grapes it can be a little time consuming. I was making this recipe a few nights ago for a party and discovered this great trick. You can easily halve two cups of grapes with ONE slice of the knife. (This also works well for grape tomatoes!)
First wash your grapes and put them on a tuperware lid. Make sure they are all facing the direction you want them sliced.
Place a second tuperware lid of the same size over the top and slice your knife between the two lids.
That’s it! This also works with two plates, as long as the plates have ridges on the bottom.
