To air dry peppers, begin by choosing fully ripe peppers for the best flavor. First, give the peppers a good wash. Then create a string or loop using thread and carefully pass it through the stems of the peppers. Hang them in a warm and well-ventilated area, like a sunny window or a room with good airflow. Keep in mind that air drying takes time, typically several weeks, for the peppers to completely dry. Be cautious, as the longer drying period increases the chances of spoilage or mold growth, especially in humid environments.
Red chilies are part of the capsicum family. However, they are different from bell peppers, being thinner and narrower and come in a variety of sizes, length, breadth and colors. When they grow they may be green, red or yellow. Usually, when dried or aged, many of the green varieties turn red, though yellow pepper is different.
