Lemon drop peppers, also known as "aji limon," are small, bright yellow chili peppers originating from Peru. These peppers have a distinctive citrusy flavor, with a hint of lemon zest that adds a refreshing brightness to dishes. Their heat level is moderate, typically around 15,000 to 30,000 Scoville Heat Units, which brings a pleasant kick without overwhelming other flavors. The peppers are slender, slightly wrinkled, and about two to three inches long, with a vibrant color that deepens as they ripen. Lemon drop peppers are popular in South American cuisine, often used to add depth to salsas, sauces, and marinades. When dried, they make a tangy, flavorful powder that enhances both savory and sweet recipes.
