Price is far from the only variable at the Greenmarket: You have to factor in crop variety, farming practices, and location. Peaches at some stands taste young right now, while others are fully peachalicious. You’ll find firm, photogenic specimens suitable for a few days of ripening, and smushy, fragrant piles of fruit begging to be sliced right into a pie crust. Shop around, and disregard those signs prohibiting squeezing.
