Get Grade A produce? A friend of mine told me that the top quality produce is sold to restaurants and that the produce found in supermarkets is B-grade. That is why, for example, you might see a bin of oranges at the supermarket and every single orange has a slight blemish--because it is a Grade B orange.

So, if this is true, how can I get high quality produce? By "high quality" produce, takes apples, for example. There are 4 different standard USDA grades:


Extra Fancy
Fancy
No. 1 
Utility


Most supermarkets sell either Fancy or No. 1 apples, not extra fancy. By high quality, I mean the highest quality of produce, no ripeness problems, no blemishes.

In Boston where I am located I heard that there is an open market in Haymarket where you can get good quality produce. Is that the only way? Find large commercial open markets?
Given that US produce grading is voluntary (see:http://www.ams.usda.gov/grades-standards/vegetables), I think your task of sourcing the highest quality produce would be one of searching, asking around...basically trial and error. It, of course, depends on how you define quality (as the comments above suggest).  If it is perfect cosmetic appearance, then yes, large commercial farms are the way to go.  If perfect is flavor, then perhaps small producers specializing in specific crops might be the way to go.
