*5 pounds is about 9-10 large apples, but apple size varies so much that you may wish to weigh at the store or market where you buy to get close. A little variance up or down, however, is fine. I like a mix of tart and sweet apples, and I don’t worry if there’s a little skin left on the apples after peeling. It will get pureed at the end and doesn’t change the flavor.
A few more things:
•If you enjoy a more assertive flavor in your apple butter, feel free to lightly round your spoons when measuring the spices.
•My slow cooker is wide, so when using the immersion blender in it, I tilt the cooker to one side. This creates a deeper “pool” to blend into, and then I use the lid as a shield against any splatters. If you have a rounder, deeper cooker, you likely won’t need to do this.
•The apples break down to the point that you could forego the pureeing step if you enjoy a less smooth final product.
