Species: Capsicum baccatum
Common Names: Aji Amarillo, Peruvian Yellow Chilli, Aji Escabeche
Type: Heirloom
Origin & Lineage
Geographic Origin: Native to Peru; cultivated across the Andean region including Bolivia and Ecuador
Development History: Aji Amarillo is one of the oldest and most culturally significant chilli cultivars in South America. Archaeological evidence suggests its use dates back over 4,000 years, with depictions found in pre-Columbian pottery and textiles. The name “Aji Amarillo” translates to “yellow chilli,” though ripe pods are typically deep orange. It remains a cornerstone of Peruvian cuisine and is featured in nearly every traditional dish, from stews to sauces.
The cultivar has been passed down through generations of farmers in the Andes, selected for its fruity flavor, vibrant color, and moderate heat. It is recognized by the International Plant Genetic Resources Institute (IPGRI) as a key genetic resource within the Capsicum baccatum species.
Cultural Significance: In Peru, Aji Amarillo is considered the soul of the national kitchen. It’s used in iconic dishes such as ají de gallina, papa a la huancaína, and rocoto relleno. Its bright color and complex flavor make it indispensable in yellow sauces and pastes. The pepper is also a symbol of cultural identity and culinary pride, often grown in home gardens and local farms.
Lineage / Hybridizer History: Aji Amarillo is a non-hybrid, open-pollinated heirloom cultivar. Its lineage traces directly to Andean baccatum landraces, with minimal genetic modification over centuries. The cultivar has adapted to high-altitude growing conditions and is known for its resilience and productivity. Its botanical traits—elongated pods, thick walls, and citrus aroma—are consistent across regional variants.
Heat Profile
Scoville Rating (SHU): 30,000–50,000 SHU
Perceived Heat: Medium—noticeable warmth with a fruity finish
Heat Characteristics: The heat is smooth and well-integrated, starting with a gentle tingle and building into a warm glow. It’s concentrated near the seeds and placenta but rarely overwhelming. Cooking softens the burn and enhances the pepper’s sweetness, while drying intensifies both heat and aroma.
Flavor Profile
Tasting Notes: Aji Amarillo peppers offer a bright, fruity flavor with notes of mango, passionfruit, and citrus. The flesh is juicy and aromatic, with a slight bitterness that balances the sweetness.
Aftertaste / Finish: The finish is clean and tangy, with lingering fruitiness and a mild herbal edge. Roasting deepens the flavor into caramel and dried apricot tones, while blending into sauces adds creamy depth.

Culinary & Cultural Use
Traditional Uses: Aji Amarillo is central to Peruvian cuisine. It’s used fresh, dried, or as a paste in nearly every traditional dish. Its flavor defines the country’s signature sauces and stews, and it’s often blended with cheese, garlic, and oil to create creamy condiments.
Raw vs Cooked Flavor: Raw pods offer bright fruitiness and moderate heat. Cooking—especially roasting or sautéing—enhances sweetness and reduces bitterness. Drying concentrates flavor and heat, while fermentation adds tang and depth.
Regional Dishes:
Ají de gallina (creamy chicken stew)
Papa a la huancaína (potatoes in yellow sauce)
Ceviche with Aji Amarillo paste
Grilled meats with Amarillo marinade
Aji Amarillo marmalade with citrus zest
Storage / Drying / Preserving Tips:
Best preserved through drying or paste-making. For drying, slice and dehydrate at low temperatures. Store in airtight containers away from light. Fresh pods can be blended into paste and frozen. Pickled pods retain color and flavor for up to 12 months when refrigerated.
