I can't remember the last time I ate applesauce from a plastic cup or out of a glass jar from the grocery store. Nor do I feel comfortable buying all the packaging just for applesauce. The taste difference between store bought and homemade are so vast that unless you try homemade you'll be fine with the tasteless liquified stuff you buy at the store. However once you make it from scratch....you'll never touch the other again.
Over low heat in a large pot simmer your apples in about 4 cups of water. Allow it to cook down until it turns into the "applesauce" texture. Strain through a sieve or food mill if you left the skins on previously. Add 1/2 cup brown sugar and 1 tsp cinnamon. Serve warm or cold. That's right folks...that's it.
