I buy apples pretty much every week in the fall/winter. Local upstate NY apples are fantastic, and they make a really convenient snack. I don't, however, always end up eating my convenient snack and it gets a little beat up in my bookbag, then I don't want to eat it because I'm picky like that. In order to avoid throwing out all these otherwise delicious but somewhat imperfect apples, I make apple sauce! The first time I wanted to make apple sauce I set out looking for a recipe and they were all COMPLETELY RIDICULOUS! Tons of sugar and all sorts of random steps. I winged it. It worked. Around here, we like our applesauce chunky, but if you prefer smooth, by all means take an immersion blender to it, or wait for it to cool a bit and blend it in a regular blender.
4 apples, peeled, cored, and roughly diced
1/4 cup water
1/4 tsp cinnamon
1. Put the apples and water in a 2 quart sauce pan and bring the water to a boil over high heat.
2. Reduce the heat to medium low, cover the pot, and cook for 30 minutes, stirring occasionally. (The more you stir the more the apples with break down. I find I don't even need to mash them at all, but again, depending on how you like it you may want to take a potato masher to it or puree it)
3. Stir in the cinnamon. Serve hot or cold.
