Pepper Jack
Pepper Jack is a spiced variant of Monterey Jack in which diced chilli peppers—commonly jalapeño, and sometimes serrano, habanero, or mixed peppers—are distributed through the mild, semi-soft cow’s-milk paste. The base cheese remains buttery and melting; the peppers add heat, vegetal aroma, and flecks of green or red throughout the ivory curd. It is used wherever a mild melting cheese needs a built-in kick: nachos, quesadillas, burgers, omelettes, and snack trays. Heat level varies by producer, from gentle warmth to sharp spice, while the underlying Jack texture stays shreddable and stringy when hot.
Also known as: Jalapeño Jack, Hot Pepper Jack

History
Monterey Jack became established in California as a mild pressed cow’s-milk cheese, creating the base style later flavoured with peppers.
Southwestern and Tex-Mex cooking popularised chilli-flecked Jack as a retail and food-service melting cheese.
National brands rolled out Pepper Jack blocks and shreds in supermarkets across the United States.
Hotter pepper blends and artisan versions with roasted or smoked chillies expanded the category beyond mild jalapeño Jack.
Craft dairies paired farmstead Jack with regional chillies, while industrial shreds remained a fast-casual staple.
