Manzano chile peppers are relatives of the hot and spicy South American rocoto pepper. Manzano chiles are thick and round, mirroring the shape of an apple like their name implies; manzano is the Spanish word for apple tree. Manzano chiles are often used fresh due to their size and are also great for making hot salsas. Manzano peppers generally rate between 12,000 and 30,000 Scoville units. Heat up your dinner table with these peppers; they pair perfectly with grilled chicken or fish.
