Long, narrow, and nearly black-green at full maturity, the chilaca is one of those peppers that rewards patience. Most fresh chiles look their best at the red stage, but the chilaca hits its flavor peak when the skin turns a deep, almost chocolate-brown green - wrinkled, glossy, and dense with earthy aroma.
At 1,000–2,500 SHU, the heat sits at the lower end of the medium SHU intensity band, making it approachable for cooks who want depth without fire. The burn is gentle and slow-building, nothing like the sharp sting of a serrano.
Pasilla Pepper
earthyrichC. annuum
Pasilla sits in the medium heat intensity range - warm enough to notice, gentle enough to let flavor lead. The heat arrives slowly, more like a lingering warmth in the back of the throat than a sharp bite.
Fresh, the pepper is called chilaca - a long, slender, dark green to near-black pod that can reach 8-10 inches. The name "pasilla" (meaning "little raisin" in Spanish) refers specifically to the dried form, which wrinkles and darkens to a deep brown-black.
Chilaca Pepper (Capsicum annuum) and Pasilla Pepper (C. annuum) come from different species, giving them fundamentally different flavor profiles.
Chilaca Pepper brings earthy and rich notes, so it fits recipes where that flavor should remain visible.
Pasilla Pepper leans earthy and rich, which can change the sauce, filling, marinade, or garnish even when the heat range looks close.
Culinary Uses for Chilaca Pepper and Pasilla Pepper
Chilaca Pepper
Fresh chilacas are most often roasted directly over a flame or under a broiler until the skin blisters and blackens. Peeled and sliced into strips, they become rajas - a classic preparation that pairs the chile's earthy richness with crema, corn, and cheese.
For building depth in chili or braised dishes, chilacas add a background richness that bell peppers can't replicate. The sensory profile of the fresh-to-dried transformation is worth understanding: dried pasilla negro carries concentrated versions of the same earthy, slightly fruity notes present in the fresh chile, which is why the two are used interchangeably in some recipes.
Dried pasilla chiles need rehydration before most uses. Toast them briefly in a dry skillet - 30 seconds per side until fragrant - then soak in hot water for 15-20 minutes.
The rehydrated flesh blends into mole negro, enchilada sauce, and adobo marinades. Its earthiness pairs naturally with chocolate, cumin, and dried fruit.
For mole negro, pasilla typically combines with mulato and ancho. Each contributes differently: pasilla handles the earthy bass note, ancho the sweetness, mulato the mid-range depth.
Start near 1:1 by amount. The heat ranges are close enough that flavor, form, and recipe role matter more than a strict Scoville conversion.
Growing Chilaca Pepper vs Pasilla Pepper
Growing notes
Chilaca Pepper
The hardest part of growing chilacas isn't germination - it's getting the pods to reach full dark-green maturity without losing them to fungal issues. The long, thin fruit tends to trap moisture against the skin, especially in humid climates, which invites anthracnose and soft rot late in the season.
Good airflow matters more with chilacas than with most medium-heat varieties. Space plants at least 18–24 inches apart, and avoid overhead watering once fruit sets.
The plants prefer warm days (75–85°F) and do best in well-draining, slightly acidic soil with consistent moisture. They're not drought-tolerant - irregular watering causes the long pods to crack.
Growing notes
Pasilla Pepper
Pasilla plants are tall growers, often reaching 24-36 inches with good support. Start seeds indoors 8-10 weeks before last frost - the long growing season (roughly 80-85 days to maturity) means early starts matter.
Transplant after soil temperatures stabilize above 60°F. Space plants 18-24 inches apart - they branch outward as they mature, and crowding invites fungal issues on the dense foliage.
Water consistently but avoid waterlogged soil. These plants are somewhat drought-tolerant once established, but irregular watering during pod development causes blossom drop and misshapen fruit.
Where They Come From
Origin & background
Chilaca Pepper
Mexico · Capsicum annuum
The chilaca's roots are firmly pre-Columbian. Capsicum annuum peppers were cultivated across Mesoamerica for thousands of years before Spanish contact, and the chilaca was among the varieties developed in central and western Mexico, where the climate and altitude of the Bajío region favored long, thin pod types.
The name itself is believed to derive from the Nahuatl word for "old" or "gray-haired," a reference to the wrinkled, darkened skin of a mature pod. Spanish chroniclers documented dark-fruited chiles in the 16th century, though precise variety-level records are difficult to trace.
Origin & background
Pasilla Pepper
Mexico · C. annuum
Pasilla peppers trace back centuries in central and southern Mexico, particularly Oaxaca and Michoacán, where dried chiles formed the foundation of complex regional sauces. The deep-rooted Mexican pepper tradition embraced pasilla as an essential mole ingredient long before Spanish contact documented it.
One persistent naming confusion: in California and parts of the American Southwest, fresh poblano peppers are sometimes mislabeled "pasilla." In traditional Mexican usage, pasilla refers strictly to the dried chilaca.
Buying & Storage
Whether you’re shopping for Chilaca Pepper or Pasilla Pepper, the same quality indicators apply. Fresh peppers should feel firm and heavy for their size, with taut, glossy skin and no soft or wet spots. Minor stem cracks known as “corking” are perfectly normal and often indicate a mature, flavorful pod.

This is not a normal versus page. Chilaca is the fresh green pod; pasilla is the dried form, so the decision is form, moisture, and cooking method rather than competing cultivars.
Water Loss Changes The Recipe
Drying concentrates the chile and removes the vegetable part of the bite. That is why pasilla can make a blender sauce taste dark and deep without adding much fresh pepper texture.
A fresh chilaca still carries water, skin, and walls. Roast it and the flesh collapses into strips for rajas, tacos, eggs, and cheese fillings. Dry it and those same walls become the wrinkled pod that needs toasting and soaking.
Both sit around 1,000-2,500 SHU, so heat does not explain the difference. The capsaicin is mild either way; dehydration changes aroma, color, and how the pepper thickens food.
If a recipe has a skillet step and wants pieces of pepper, start with chilaca. If it has a blender step and wants a dark sauce, start with pasilla.
Rajas Or Blender Choice
Rajas belongs to chilaca. The pod is long, narrow, and thin-walled enough to blister quickly, then peel and slice into strips that still feel like a vegetable.
Pasilla belongs to the blender or grinding stone. A toasted and soaked pod gives salsa, mole, adobo, and braising liquid a wine-dark color and a dried-fruit edge. That is closer to the decision in pasilla vs poblano than to a fresh-pepper salsa choice.
Use that physical test before substituting: if the pepper must be seen and chewed, chilaca wins. If the chile needs to disappear into sauce, pasilla wins.
Swap Only After Rebuilding Liquid
A fresh chilaca can replace pasilla only after roasting, peeling, and reducing extra liquid elsewhere in the recipe. Otherwise a mole or salsa can turn thin and green instead of dark.
A pasilla can replace chilaca only when the dish can lose fresh texture. Rehydrate, puree, and add it as sauce; do not expect it to stand in for strips in eggs, rajas con crema, or a stuffed pepper. The dedicated pasilla substitute path is safer when the recipe is already dried-chile based.
Market Name Trap
Shopping names cause most confusion. Fresh chilaca is often rare outside Mexican markets and Southwest specialty produce. Pasilla is much easier to find dried, but some stores mislabel ancho as pasilla.
Check shape before trusting the bag. Pasilla should look long, dark, and wrinkled; ancho is wider and heart-shaped. The Pasilla de Oaxaca comparison is another separate label issue because that chile is smoked and hotter.
For storage, treat chilaca like fresh produce and use it within days. Treat pasilla like a dried spice: airtight, dark, and flexible enough that the pod still bends.

Chilaca Pepper vs Pasilla Pepper FAQ
Yes - the pasilla is the dried form of the chilaca pepper. The name changes with the form, which is a common convention in Mexican cuisine where fresh and dried versions of the same chile are treated as distinct ingredients.
Not directly - fresh chilaca lacks the concentrated chocolate and raisin notes that develop during drying, and mole depends on those dried flavors. You would need to use a dried pasilla (or ancho as a backup) to get the right flavor profile in a traditional mole negro.
Pasillas are longer and narrower with near-black, wrinkled skin and a raisin-like aroma. Anchos are wider, heart-shaped, and smell more like dried fruit and tobacco - they are the dried form of the poblano, not the chilaca.
At 1,000-2,500 SHU, both forms sit at a level most people find very manageable - roughly equivalent to a mild Anaheim pepper. People who avoid heat entirely might notice a gentle warmth, but neither form is considered spicy by any reasonable standard.
Fresh chilacas are uncommon outside of Mexico and specialty Latin markets in the US, particularly in areas with large Mexican communities. Dried pasillas are far easier to source - most well-stocked grocery stores carry them in the international or spice aisle.
