Get some good baking type apples. Peel and slice. I like the little cranking machine that cores and peels, as well as slices all in a few turns of the crank. To can, you must use acorbic acid to prevent oxidation. Adding citric acid or lemon juice is also necessary. The apples are cooked a bit using sugar to your taste. If you wnat more apple taste, add a can of frozen concentrated apple juice. Clear Jel is the modified starch used as a thickener. Only thicken slightly, so its density isnt too heavy. If more thickness needs to be done, that can be at the pie making stage. Its up to you as to spices, most commonly cinnamon. Also, Alton Browns favorite is 'Grains of Paradise' which as a peppery flavor.

Trudy, the beauty of only a bottom crust is that if it looks ugly or tears or whatever, you patch it and cover it with apples. If you want a top crust and it doesn't go well, just cut circles or diamonds or strips or little apples or whatever and put them on top and pretend you meant to do that! Those tiny cookie cutters are finally good for something, LOL. mare, thank you. It did taste as good as it looks and didn't last as long as I thought it would. (grin) I did post the recipe for Trudy on another thread but I'd be happy to post it again. I made it from this recipe, but skipped the top crust and instead of the powdered sugar/milk glaze made a maple glaze from powdered sugar, maple syrup and some maple extract (to taste). I also left out the cornflakes as I didn't have any and usually don't have any. It's good with or without them. The extra crust makes a second slab, or a top crust, your choice. It keeps for a couple of days in the fridge. Mine became a second apple "slab" as the first one was so good. The original recipe, I think, came from Midwest Living. Apple Slab 2 1/2 cups all-purpose flour 1 teaspoon salt 1 cup shortening 1 egg yolk Milk 1 cup cornflakes 8 -10 tart cooking apples, peeled, cored and sliced (8 cups) 3/4-1 cup granulated sugar 1 teaspoon ground cinnamon 1 egg white, lightly beaten 1 cup powdered sugar 3 -4 teaspoons milk In a large bowl combine flour and salt. Using a pastry blender, cut in shortening until the mixture resembles coarse crumbs. In a liquid measuring cup, beat egg yolk lightly. Add enough milk to make 2/3 cup liquid. Stir well to combine. Stir milk mixture into flour mixture with a fork until combined (dough will be slightly sticky). Divide mixture in half. On a well-floured surface, roll half of the dough to a 17x12-inch rectangle. Fold dough crosswise into thirds. Transfer to a 15x10x1-inch baking pan and unfold dough, pressing to fit into the bottom and sides of the pan. Sprinkle with cornflakes. Top evenly with apples. In a small bowl combine granulated sugar and cinnamon. Sprinkle mixture over apples. Roll remaining dough to a 15x10-inch rectangle. Fold dough crosswise into thirds. Place atop apples and unfold dough. Crimp edges or use the tines of a fork to seal. Cut slits in the top. Brush top with beaten egg white. Bake in a 375 degrees F oven for 50 minutes or until golden and apples are tender, covering with foil after the first 25 minutes of baking time to prevent overbrowning. In a small bowl combine powdered sugar and 2 to 3 teaspoons milk to make a drizzling consistency. Drizzle over warm bars. Let cool completely on a wire rack. Cut into bars. Makes 32 bars. Annie

What exactly is "approved" sources? I don't imagine the government approves any sources other than themselves, so who is doing the approving? Is there some kind of list somewhere you are referring to? Or do you mean only use recipes listed on the NCHFP website? The Ball Corporation (Jarden in Canada) publications on home canning have been held as THE approved source for over 100 years. The are often referred to as the canning bible and are well known for their ongoing research and updated publications on safety issues. This was long before the USDA or FDA came into existence. Also for decades Rodale Publishing was also regarded as totally safe in their canning publications. Unfortunately they quit maintaining the currency of their canning publications when NCHFP was created but with a few exceptions most of their publications are still valid. In addition there are the USDA and FDA publications, all the publications from NCHFP, all the publications from the many land-grant university extension services, and many publication from well-known food scientists such as Linda Ziedrich, Ellie Topp, Margaret Howard, etc. People who have the educational credentials and research background to know what they are talking about as opposed to the many bloggers and authors that merely subscribe to the "it hasn't killed anyone yet" school of science. There are a number of discussions here about what constitutes approved sources, which books are approved and which should be avoided, and reviews of various canning blogs pro and con. There used to be a number of MFP's (Master Food Preservers) that participated here on a regular basis and we made a concerted effort to review new publications and websites as they came up. Unfortunately Deanna and I are the only ones we have heard from since the move to Houzz but all that past info from the others is still available here and classes are available to anyone who wishes to takes them through their local county extension service. If you don't want to invest the time in getting the MFP credentials then take some basic classes or even the basic online course offered by NCHFP is a place to start. Honestly I find a lot of this kind of arbitrary. I'm sure it does seem that way when one is new to the process or has none of the underlying science training. But they aren't arbitrary. There are valid reasons, based in research and testing for all these guidelines. So everyone is left choices: (1) to either get the training so that they do understand it all and know where changes can and cannot be made (2) or accept them at face value and do them in order to have the assurances of safety they provide (3) or to challenge, question, ignore, and criticize them and just do their own thing when it comes to canning as long as they willingly accept the associated risks that come with that approach. The internet has plenty of blogs and forums that have adopted #3 approach and preach against the accepted guidelines. In some cases it is because they don't know any better, in some cases it is because they don't care, and in some cases it is because they claim to hate the government and reject all that it stands for or represents. This particular forum has long had the reputation of being safety oriented, or rejecting the make-it-up-as-you-go-along canning methods, and a place where those new to home canning can get safe advice. Are the guidelines perfect? Of course not. But they are the best and safest options we have available. Dave

I'll move, to be your neighbour, Martha!! I make Ina's Apple Crostata when I want apple pie. I've made it for years, it's so easy! But once in a while a 2-crust pie fits the bill (and in my mind, the crust is the best part). I use her recipe for that too.
