Dried Chili Peppers (干辣椒)
Dried chili peppers (干辣椒, gan lajiao) are a fundamental ingredient in Sichuan, Hunan, Guizhou, and Yunnan cuisines. Chinese dried chilies are typically milder than their Mexican or Southeast Asian counterparts, with heat levels ranging from 10,000 to 50,000 Scoville units. The most commonly used varieties include facing heaven chilies (朝天椒, chaotian jiao), Erjingtiao (二荆条), and bullet-head chilies (子弹头). They are valued not just for heat but for their specific fruity, earthy, or smoky flavors and their ability to infuse oil with color and aroma. In Chinese cooking, dried chilies are typically fried whole in oil as the first step, releasing fragrance without excessive heat. Western dried chilies have different flavor profiles and heat levels, making direct substitution imperfect.
Chile de Arbol
Ratio
1:1 by count for most Chinese dried chili types
Flavor Change
Chile de arbol is the closest widely available Western substitute for Chinese dried chilies. The heat level (15,000-30,000 Scoville) overlaps with many Chinese varieties, and the thin-walled, small shape is similar. The flavor is slightly more nutty and less fruity than Chinese facing heaven chilies, but the difference is subtle when fried in oil.
How to Compensate
Remove seeds for less heat (Chinese recipes often use whole chilies with seeds for moderate heat). If the recipe calls for the milder Erjingtiao variety, use fewer chiles de arbol or remove all seeds. Toast them briefly in oil just as you would Chinese dried chilies.
Guajillo Chilies (for Erjingtiao) or Japones Chilies (for Chaotian)
Ratio
Guajillo: 1 guajillo per 2-3 Erjingtiao (guajillos are larger); Japones: 1:1 for facing heaven chilies
Flavor Change
Guajillo chilies share the mild heat (2,500-5,000 Scoville) and fruity character of Erjingtiao peppers, the variety used in many Sichuan dishes for flavor and color rather than intense heat. Japones chilies are thin, hot, and similar to Chinese bullet-head chilies. Neither is an exact match, but both capture the essential character for stir-fries and chili oil.
How to Compensate
For guajillos: cut into segments similar in size to Chinese dried chilies before frying. They are thicker-walled, so they need slightly longer toasting. For japones: use the same technique as Chinese dried chilies — fry until darkened but not burned.
Red Pepper Flakes (Crushed Red Pepper)
Ratio
1/2 to 1 teaspoon red pepper flakes per 5-6 whole dried chilies
Flavor Change
Red pepper flakes provide heat but none of the whole chili experience — no visual presence, no oil infusion, no toasted fragrance. The heat profile is also different: flakes release their heat immediately while whole dried chilies release it gradually. The dish will taste spicy but lack the aromatic, fruity complexity that fried whole chilies provide.
How to Compensate
Add the flakes to hot oil and fry briefly (10 seconds) to develop some toasted flavor. Consider adding a small pinch of smoked paprika for the aromatic dimension. This is a last-resort substitution — whole dried chilies of any variety are far preferable.
Where to Buy
Chinese grocery stores (sold in large bags, very inexpensive — usually under $3 for a large bag that lasts months). Online: Amazon carries Tianjin chilies, facing heaven chilies, and Erjingtiao varieties; Mala Market specializes in high-quality Sichuan dried chilies with specific variety names; Weee! stocks several Chinese brands. For the best selection, visit a physical Chinese grocery store where you can inspect the chilies — they should be pliable (not brittle), deep red (not brown), and aromatic when sniffed. Store in a sealed bag in a cool, dark place for up to 12 months.
FAQ
What kind of Chinese dried chili should I buy for Sichuan cooking?
For general Sichuan cooking, buy facing heaven chilies (朝天椒, chaotian jiao) — they offer moderate heat and good flavor, and are the most commonly used variety. For Kung Pao chicken and many classic Sichuan stir-fries, Erjingtiao (二荆条) are the traditional choice — milder with a fruity, fragrant character. For maximum heat, bullet-head chilies (子弹头) are used. If the variety is not labeled, the small (2-3 inch), slender, bright red chilies with moderate heat are the standard all-purpose type.
Should I remove the seeds from dried chilies?
It depends on your heat tolerance and the recipe. Chinese recipes often use whole dried chilies with seeds for moderate heat and visual appeal. Removing the seeds and inner membranes reduces heat by about 50-70%. For dishes like Kung Pao chicken, the traditional approach is to cut the chilies into 1-inch segments, shaking out some but not all seeds. For chili oil, seeds are typically included for heat and texture.
Can I use fresh chilies instead of dried?
Not as a direct substitute — the cooking technique and flavor are fundamentally different. Dried chilies are fried in oil to release aromatic compounds and infuse the oil with color and flavor, a technique called '炝锅' (qiang guo). Fresh chilies release water and do not achieve the same toasted, concentrated flavor. If a recipe calls for dried chilies to be fried in oil as the first step, there is no fresh chili substitute that replicates the technique.
