Modern commercial apple varieties universally feature thin skins, but
many of the best tasting apple varieties have rough, potato-like
skins. They are called "russets". The russets have been cultivated
not for their surface appearance but in spite of it; beneath the
rough exterior the flesh is richly flavored often with a spicey
quality, and the texture is robust.
Like many of the russets we tasted, the texture and flavor
of the fall russet reminded us of a pear.
