If you feel like this recipe might make more than you can eat and you don’t want to follow canning procedures, you can easily halve or quarter the recipe. I would pressure cook for 3 minutes for half the amount, or 2 minutes for a quarter of the amount. If you want to make it on the stove, it will also take less time. But just check the apples sooner.They’re ready when you can easily mash a fork into them.
