Why are some apples mealy while others are crisp?
Cornell apple breeder Susan Brown answers that question in this New York Times science Q&A.
The differences are partly genetic, she explains. Some varieties can be stored longer before they get mushy.
But proper storage at home will help you keep your apples crisp. “If consumers store fruits at room temperature, rather than in the refrigerator, they will soften and get mealy sooner,” she says.
