I love this picture :) Baby Red Delicious Apples! And trust me, though you may think this variety is boring and un-flavorful, I bet you'd change your mind if you tried it fresh off a tree!
A Quince. Can you tell it has a fuzzy skin to it? Kind of like a peach. Once they ripen, the fuzz comes off and they are a shiny lime-yellow color. And they smell like sweet pineapple as you walk through the orchard.
This is frost damage on a pear :/ It really doesn't hinder the flavor of the fruit, it just leaves unsightly brown blotches.
