Ancho Powder: Ground Dried Poblano, Its Heat, Flavor and Uses

Ancho powder is ground ancho chile, and an ancho is a dried poblano.¹ It is a mild chile, and New Mexico State University’s Chile Pepper Institute describes its flavor as sweet and smoky with hints of dried fruit.¹ This page covers what ancho is, how hot it is (the figures depend on what was measured), how it is used, and what its nutrition and safety records show.

At a glance

Ancho, poblano and the name

A poblano is the fresh green chile; dried, it becomes an ancho. The Chile Pepper Institute (CPI) at New Mexico State University puts it simply: anchos are dried poblanos, Capsicum annuum, with dark, wrinkled skin ranging from reddish-brown to almost black.¹ The Codex international standard for dried chile lists “Ancho” among the varietal names of chilli pepper it covers.³ For which ripeness stage poblanos are picked at before drying, no source was checked for this page.

Poblano is Spanish for “of Puebla”: the Real Academia Española defines it as belonging or relating to Puebla or its people.⁶ The name links the chile to the Mexican state of Puebla, but no source checked for this page shows that the poblano type was developed there. The species itself is native from the southern United States to Brazil and the Caribbean,⁷ and a 2014 study found that four independent lines of evidence point to its domestication in central-east Mexico.⁴

Ancho powder made from a single chile is a different product from American chili powder, which is a blend; Saveur notes that the chile in most chili powder blends is usually ancho.⁸

Flavor

CPI describes ancho as having sweet, smoky flavors with hints of dried fruit.¹ PepperScale describes an earthy sweetness with subtle notes of raisin and coffee.⁹ In a sauce the powder reads as raisin and prune, with a slight bitterness and gentle warmth; that description is editorial. The often-repeated claim that ancho is the sweetest of all dried chiles could not be traced to a source.

How hot is ancho?

How to read this:

• CPI’s 1,000–2,000 is a general figure for the pepper type, not a measurement of any particular lot or powder.
• The Minnesota figures describe fresh fruit of specific cultivars, grown in one place in one year, measured with a ChilliPot device that the authors describe as an electrochemical method whose correlation with the standard HPLC method “has not been proven.”¹⁰ They do not show that CPI’s range is wrong, and they are not figures for dried ancho powder.
• The Codex threshold is a category boundary, the line the standard draws between hot paprika and chilli pepper, not a measurement.³
• The 1,000–1,500 range is attributed, not measured. It matches Dave DeWitt’s approximate heat scale,¹¹ which cites no measurement, and PepperScale gives the same range.⁹ NMSU notes that HPLC is the most accurate way to measure chile heat and that Scoville taste tests are subjective.¹²

In our judgment, ancho is mild enough to measure by the teaspoon or tablespoon rather than the pinch, but taste as you go.

How it is used

Mole. CPI calls ancho a key ingredient in Mexican mole sauce.¹ El Universal lists ancho alongside mulato, pasilla and chipotle among the chiles in mole poblano.⁵ By common practice, whole pods are toasted, soaked and blended for mole, and powder is a shortcut. See mole powder.

Sauces, stews and marinades. CPI notes that ancho is commonly used ground for seasoning or rehydrated in sauces, stews and marinades, and that it pairs well with chocolate, tomatoes and meats.¹ Common uses for the powder, as kitchen practice rather than sourced findings:

• Red enchilada sauce and chili; see best spices for chili. PepperScale calls ancho a staple in mole and enchilada sauces.⁹
• Dry rubs for pork, beef and chicken, often with cumin and a little sugar.
• Beans, braises and soups, where it adds color and body.
• Sweet uses with chocolate, as in CPI’s ancho-orange hot fudge recipe.¹

Pairings. Ancho works well with cumin, cinnamon, Mexican oregano, garlic, cocoa and cilantro. That list is cooking judgment, apart from chocolate, tomatoes and meats, which CPI names.¹ PepperScale adds lime, whose acidity it says cuts through ancho’s smoky sweetness.⁹

Technique. Like other ground chiles, ancho powder burns easily; warm it briefly in oil over moderate heat before adding liquid. Kitchen practice, not a sourced finding.

Buying and quality

• Color and aroma. Good ancho powder is deep brick-red to mahogany and smells fruity. Gray-brown, dusty powder has faded. Kitchen judgment.
• Check the label. Pure ancho powder lists only ancho chile; a jar that also lists cumin, oregano or salt is a blend.
• Whole pods. CPI describes anchos as dark and wrinkled, reddish-brown to almost black.¹ Pods that are still pliable rather than brittle are generally fresher, in our judgment, and can be toasted and ground at home.

Storage

Keep the powder airtight, dark and cool. No shelf-life figure from a regulator or standards body was found for ancho powder; figures that circulate online could not be traced. If the color has dulled and the fruity smell is gone, replace it.

Nutrition and health

USDA FoodData Central has an entry for whole dried ancho peppers, with one pepper weighing 17 g; it has no entry for the powder and gives no tablespoon weight.² Per pepper, that works out to:

A whole pepper is a lot of ancho for one serving; a teaspoon of powder in a dish for four supplies far less. Figures that circulate for a tablespoon of ancho powder (such as 69% of daily vitamin A) could not be traced, and USDA gives no tablespoon weight from which to check them.

Capsaicin. The strongest human evidence concerns a prescription skin patch, not chile in food. A 2017 Cochrane systematic review found moderate-quality evidence that a high-concentration (8%) capsaicin patch gave moderate pain relief to a minority of people with postherpetic neuralgia, with very low-quality evidence for other nerve pain.¹⁴ Claims that eating ancho relieves arthritis or psoriasis pain through endorphins, suppresses appetite or prevents prostate cancer were not supported by any source reviewed for this page. No claim is made here that ancho treats or prevents any disease.

Safety

• Mycotoxins (EU). EU law caps ochratoxin A at 20 µg/kg in dried Capsicum fruits, whole or ground, and sets 5.0 µg/kg for aflatoxin B1 and 10.0 µg/kg for total aflatoxins.¹⁵
• Handling. Even mild chile powders irritate eyes; wash hands after handling. Common-sense guidance, not a sourced finding.
