I eat 2-3 apples a day and use them in various recipes - usually desert or pork related.
I have found that I am literally terrible at picking out apples though and seem to be getting no better.
What I am looking for:
Crisp - this is a deal-breaker for me. If it is mushy, I don't want it. I have a hard time eating a slightly mangy apple no matter the actual taste of it. These have to get mashed up into a dish.
Sour - I would like the apples to be as sour as possible - within reason. I have never had an apple be too sour so I going with the assumption that anything goes here.
Sweet - Not overly sweet and not overpowering honey taste but sweet.
Thin skin - I like the skin. I however don't like to be able to measure the thickness of the skin.
I am looking for what type of apples (I have a few favorites but even in those it is hit or miss), season, size, coloring, or anything else that helps identify a good from a bad apple.
