Add cinneman to taste. You can also add other spices like those found in mulling drinkings. Put the pot on a stove at low heat. Within 30 min. It may help if you use a potato masher.
Some apples are beter than others.
You could always use a food processor to break up the apple sauce after it has cooled. Often my fruit is quite dry and hard. Perhaps if the drying is done very slowly, is it possible to get fruit like the apricots that you'll see in a store. The taste of the fruit can change with drying. I've had very bland apples that tasted wonderful when dried and also had good tasting apples turn into very bland dried fruit.
