Where I live, all of the brands of commercially-available applesauce that I've found come in irregularly shaped jars. There's a narrow section in the middle of the jar which makes it hard to reach the sauce underneath the narrow part:
There are also indented rings just above and below the narrow section offering another place for sauce to get trapped.
To make matters worse, the areas that the front and back labels attach to are ribbed, making it awkward and time-consuming to get all the sauce from there:
I know that I can put some water in the jar, put the lid back on and shake it to get most of the remainder out, but that leaves me with watery applesauce.
With all of these challenges, how can I get all of the applesauce out of the jar?
