Hatch Peppers have thick skin that is smooth and glossy, ripening from green to dark red when mature. Underneath the surface, the semi-thick flesh is crisp, pale green, and aqueous, encasing a central cavity filled with thin, white membranes and round and flat, cream-colored seeds. These Hatch Peppers have a bright, earthy, and grassy flavor when fresh with extra hot spice. Once the peppers are cooked, they develop a rich, smoky flavor.
