This picture of the Ruby Jon apple does not do its color justice: the Ruby Jon Apple is much darker and velvety in reality.
Asides form the color, the first thing I noticed about the Ruby Jon apple was the grainy-ness of the flesh. Then came the apparent dryness of the apple. Although it tasted dry there were clumps of juice scattered throughout. The consistency of the flesh and amount of juice made me think it was dry. The flavor of it was a pretty pronounced tartness, but with some sweet undertones.
The flavor of the Ruby Jon apple was fine, but the texture was highly distracting and unpleasant.
