Some apples have more air in their cells than others. It sounds as though it was too thick if it has the bubbles and separated. It will be fine, though. Applesauce should move in the jars when you gently shake them. If it doesn't, it is too thick.

My apple chunks are more 'floaty' than usual. Might be the year. My jars were actually floating in the BWB, qt jars filled correctly and at the end of the processing time, 2-3 jars were floating. I was worried about the jars possibly be broken, but that wasn't the case. This happened to 5-8 batches out of the 12-15 batches that I did. All apples were from 2 trees and it didn't matter which tree the apples were from.

All sealed fine, but I will be watching.

Thanks everyone. It does move in the jars as in previous years, just a different textural thing, I guess. Since it was just a small batch (all sealed), I put it in the refrigerator anyway. It will be used for cooking in the near future, so I'm not worried. Just curious.

Thanks again,
Sarah
