Homemade applesauce:

Use up whatever apples are lying around the house uneaten. Old, new, green, red, tart, sweet, mixtures of different kinds seem to work the best. Don't go out and buy them.

Peel, slice into any kind of big chunks or slices, the more irregular the better. Put in a pot. Put just enough water in the pot to keep the things from burning -- maybe a quarter of an inch deep.
Sprinkle with sugar or fructose, not much, maybe half-cupful for a small pot, perhaps up to a cup for a large pot. Sprinkle with cinnamon and/or mixed pie spice, maybe a teaspoon for a small pot, 2 for a large pot. Don't oversugar or spice, you can always add more later but you can't take it out.

Cover, simmer on low. Check every 10 minutes or so, stir occasionally and add a bit of water if it starts to go 'dry'. When the apples are all soft, take off the heat. Taste and see if it needs more sugar or spice. Smush with a potato masher. Leave some small chunks, it tastes better that way, don't try to get it to be a commercial puree.

This is a great thing to do because you use up fruit which might otherwise go to waste, it makes the kitchen smell great, and you have this treat which doesn't involve getting fat eating pie and strudel.
