Tips. I always use either citric acid or lemon juice to keep my apples from browning. While it doesn't change the flavor, it does keep the fruit from oxidizing and going that odd brown. The brown won't hurt you. We've just been hardwired to think it is icky or spoiled. Eventually, oxidation will change the texture and flavor, so why waste the fruit in the long run to save in the short run?
I simply add some to the water in the slicing bowl and take them for a swim/rinse before cooking them.
Those gadgets they sell to peel and core and apple for you in seconds. USELESS. They usually break smack in the middle of your project, slice apples too thin, or take longer to set up and clean than it does for you to work a peeler.
Find and buy a GOOD peeler, and then buy more of them and hoard them.
I specifically went to the NorthDakota State fair the first year we were married to do nothing BUT buy a vegetable peeler from the knife guy. I still have it and if the house was on fire, it would be one of the things I would grab. (LOL. Kidding..... but not about the peeler.) I've had it 24 years and have NO IDEA what company made it. But I can peel a large apple in under 20 seconds.
Don't bother coring with a fancy machine or a poke through core punch. Just peel your apple and cut around the core as closely as you can. Four quick motions with the knife gives you a core to toss to the compost and 4 large pieces of apple to slice, and HEY, you already have your knife in your hand to do it!
A gel mat to stand on while you peel. If you peel sitting down, you'll get lazy and rest your elbows. That will slow you down. Peel at the sink. Put the stopper in and fill the sink with cores and peels. Then scoop the whole mess into the compost or chicken bucket when you are done.
My girls don't get cores, but I DO slice up the peels and put them into sandwich baggies and freeze for winter treats.
Cover anything you don't want splashed with apple peeling juice with a dish towel. The stuff flies everywhere.
Don't' use apples that with slow you down. One year I had a batch that was overly bruised, damaged, and buggy and they were small. They too me too much time to work with. I make sure I get fist size or larger and peel like a mad woman. Music blaring in the kitchen,.
Use a mix of apples in whatever you make. The end result will amaze you. IF you can remember when apples you use, write it down for each batch you do, so you can repeat a good result.
Firm baking apples are a different creature from a good eating apple. Don't mix the two.
I will put my apple recipes on my blog sometime later today (I volunteer on Tuesdays and to day is inventory day, so keep checking it.)
I wish I had someone to come sit and learn. The Boy and DH love eating it, but aren't interested in learning. Their help slows me down, but they are good for lifting and hauling and bringing up jars, and taking jars down! LOL.
I'll be putting up some pie filling as well...found a good recipe for it online and want to try it. Should be tasty!
