Step 1: cut your apples into quarters, don't worry about the seeds, core or stem.
Step 6: Place you jars into a canning pan (usually will fit up to 7 jars- quart or pint). Make sure the water is over the jars by 1/2- 1 inch. Cover with the lid. Once the water is boiling set the timer for the processing time. (I'm at 5,000 feet so my processing time is 20 minutes for pints and 30 minutes for quarts) It's better safe than sorry and you really can't over process them in this kind of canner. Your canner will have a processing guide for items you can refer to if you are concerned about your elevation.
Here's a link where you can get the Kitchen Aid attachment like I have-KitchenAid FVSFGA Fruit/Vegetable Strainer and Food Grinder for Stand Mixers
And here's a hand crank one- Also a water bath canner like I use and some tools you'll want.
