Some friends recently shard a good sized bag of their small, sour, homegrown apples with us, so I spent parts of two days making and canning apple butter. I do it partly based on a recipe, and partly based on "feel," but here are the approximate proportions:
2 cups of apple pulp (I make apple pulp by cutting and peeling apples, cooking them over low heat until they are soft, and putting them through the blender)
1 cup sugar (or more or less, according to what you like)
2 tsp. of cinnamon
1/2 tsp. nutmeg
1/4 tsp. cloves
I mix it all into my crock pot, let it cook until it's thick, and then put the apple butter into canning jars and process them in boiling water for 15 minutes. If you are interested in canning, I would recommend the Ball book on canning. It describes the canning process and explains how to do it as well as giving many good recipes!
Little Man sat on the counter where I was working and enjoyed getting apples out of the sink for me and sampling every one. It was a win-win situation: I enjoyed his company, he enjoyed mine (and the apples), and he stayed out of trouble while I got my work done.
