I have still been researching the Mystery of the Floating Fruit here in my jars and figured I would let y'all know what I've come up with. The Ball Blue Book says this is caused bcz the fruit is lighter density than the syrup. The solution (or prevention) for this is :
(quote)
"Use firm, ripe fruit. Heat fruit before packing. Use a light to medium syrup. Pack fruit as closely as possible without crushing."
... So, my fruit could have been more ripe. Ok. I could have packed more pieces in, maybe. But I did heat first, and I used a recipe with the recommended amount of sugar (as all the food safety stuff tells us to do)... So what gives?
A Light Syrup is ~30% sugar
(2.25c sugar to 5.25c water yielding 6.5c syrup)
A Medium Syrup is ~ 40% sugar
(3.25c sugar to 5c water yielding 7c syrup)
So it's all about density, I guess.
Also, figured I should mention, this book's recipe for
apple Pie Filling yield ~6pts
6# apples
Fruit-Fresh
2c Sugar
1/4c Flour
1.5teaspoon cinnamon
0.25teaspoons Nutmeg
2Tablespoons lemon juice
Wash, peel, core & slice apples. Treat with Fruit Fresh to prevent darkening.
Combine sugar, flour and spices. Rinse and drain apples; stir into sugar mixture. Let stand til juices begin to flow, about 30mins. Stir in lemon juice. Cook over medium heat until mixture begins to thicken. Ladle pie filling into plastic
freezer jars or containers, leaving 1/2" headspace. Cool at room temperature, but do not exceed 2 hours. Seal, label &
freeze.
There ya have it... No ClearJell or Cornstarch required
