red or green hot peppers

Hot peppers—both red and green varieties—are fruits of the Capsicum species, native to Mesoamerica and now cultivated worldwide. The heat in these peppers derives from capsaicinoids, alkaloid compounds concentrated in the placental tissue and seeds, with varying intensity depending on cultivar and growing conditions. Red peppers are mature green peppers that have ripened on the plant, developing sweeter undertones alongside their pungency. Green peppers are harvested at an earlier stage and typically exhibit a more vegetal, grassy flavor with sharper heat. Common hot pepper varieties include jalapeños, serranos, Thai chilies, cayenne, and habaneros, each with distinct heat levels measured on the Scoville scale.

Hot peppers are fundamental to cuisines across Latin America, Southeast Asia, India, and parts of Africa and the Mediterranean. They are used fresh, dried, smoked, powdered, or fermented to add heat and complexity to salsas, curries, stir-fries, and braises. Red peppers are often preferred for dried applications (paprika, chili powder) due to their developed flavor, while green peppers lend a bright, grassy heat to fresh salsas and ceviche. Both colors are essential in hot sauces, pickles, and condiments. Roasting mellows the heat and adds smoky depth; charring the skin before peeling is common in Mexican and Mediterranean preparations.
