They really do make great applesauce. Just have to use a lot more of them.I read somewhere that crabapples are really just very small apples. I also read people will splice larger apple variety branches to the established "crabapple" trees and get super results. I have two down back that price apples the size of golf balls but man they are delicious! I made killer applesauce out of them one year.
And crabapple jelly is delicious.
