How-to Halve a Winter Squash
With their hard shells, winter squashes can be difficult to cut in half. Here's a method that doesn't rely just on strength. Use a rubber mallet and a large knife, such as a French chef's knife. Cover mallet with a food storage bag and secure to the handle with a rubber band or twist tie. Insert the knife lengthwise into the middle of the squash. Hold the knife handle with one hand and hit the top of the blade by the handle with the mallet. Continue hitting the knife with the mallet until the squash is cut in half.
