What Is Aji Amarillo? Heat, Flavor, Paste, and Uses

Aji Amarillo at a Glance

Aji Amarillo is a Peruvian Capsicum baccatum pepper with elongated pods, orange ripe color, and enough heat to shape a sauce without reaching habanero intensity. The common published range is 30,000-50,000 SHU.

New Mexico State University explains that laboratories measure capsaicinoids with HPLC and convert the result to Scoville Heat Units. Genetics, weather, growing conditions, and fruit age can move one pod or jar away from the headline range, so a cook should still taste before increasing the amount.

The flavor is best understood as tropical fruit with a light raisin-like depth rather than the grassy bite of a green annuum chile. We use that distinction as editorial sensory guidance, not as a claim of firsthand tasting.

Amarillo means yellow in Spanish, but the traditional name does not describe a strict final color. Ripe pods commonly deepen from green through yellow into vivid orange.

Where Aji Amarillo Comes From

Peru's Ministry of the Environment identifies Aji Amarillo, also called aji escabeche, as a cultivated C. baccatum pepper associated with the Peruvian coast. That named record is stronger evidence for identity than a broad claim that every ancient Andean chile was the same modern cultivar.

Official Peru Travel references show why the pepper remains central to the country's cooking. Aji de gallina uses a yellow chile sauce around shredded chicken, while causa carries chile through seasoned potato layers.

Ceviche and tiradito use chile differently from those creamy dishes, but the same ingredient supplies color, aroma, and a clean edge beside citrus and seafood. These named preparations explain the pepper's culinary importance more precisely than calling it a general-purpose hot chile.

The Heat and Taste of Aji Amarillo

The Aji Amarillo delivers 30K–50K Scoville Heat Units, placing it in the Hot tier (10K-100K SHU). That makes it roughly 4-20x hotter than a jalapeño, depending on where the jalapeño falls in its 2,500-8,000 SHU range.

Flavor notes: fruity, tropical, slightly raisin-like.

Aji Amarillo Nutrition Facts & Serving Context

USDA FoodData Central lists raw green hot chile peppers at 40 calories per 100 grams, with vitamin C, potassium, and fiber. That entry is general hot-chile context, not a cultivar-specific laboratory result for Aji Amarillo.

A serving also changes with the format because one sauce may divide a spoonful of paste among several plates. Nutrition data should therefore be read from the specific packaged product when salt, oil, or preservatives matter.

Capsaicin is relevant here as a handling compound, not a treatment claim. Wash hands, knives, and boards after cutting hot pods, and avoid touching the eyes or face during preparation.

Aji Amarillo in the Kitchen

Choose the form by the texture the dish needs. Fresh pods provide pieces that can be sliced, roasted, or blended, while prepared paste disappears smoothly into aji de gallina, causa, huancaina-style sauce, and marinades.

A jar of paste is the practical choice in many markets outside Peru, but brands may include different amounts of salt, acid, oil, or cooked pepper. Start with a modest spoonful, read the label, and adjust after the paste has dispersed through the sauce.

Where to Buy Aji Amarillo & How to Store

Fresh Aji Amarillo is most likely at Latin American markets, Peruvian grocers, specialty growers, or farmers markets during pepper season. Choose firm yellow-orange or orange pods without wet soft spots, mold, or collapsed skin.

Jarred paste is usually easier to find than fresh pods outside Peru. Check the ingredient list for salt, vinegar, oil, and preservatives, then refrigerate after opening when the manufacturer directs it.

Frozen pods are useful for cooked sauces because freezing preserves the ingredient while sacrificing crisp texture. Keep them sealed and labeled so they are not confused with a milder orange pepper.

Store dried pods and powder in an airtight container away from light, heat, and moisture. Replace them when aroma has faded or moisture has caused clumping, because color alone does not prove good flavor.

Growing Aji Amarillo at Home

Aji Amarillo needs the same warm start as other long-season peppers. University of Minnesota Extension recommends starting pepper seed indoors, moving plants outside only after frost risk has passed, and growing them in full sun with well-drained soil.

Steady moisture supports flowering and fruit fill, while cold nights and transplant stress can slow the crop. Gardeners with short summers can use containers or season extension so plants have more time to reach ripe color.

Harvest green pods when a recipe wants a firmer, less ripe chile, or wait for yellow-orange to orange pods when fruit character and sauce color matter most. Clip the stem instead of pulling hard enough to damage the branch.

Saved seed may cross with other flowering peppers in the same garden. Isolation is the practical choice when the next generation needs to retain the cultivar's pod shape, color, and baccatum character.
