How to Make and Use Dried Chili: Rehydrating, Storage, and Tips for Using Up Large Amounts

Dried chili peppers, made by drying red chilies, are a handy ingredient that keeps well and lets you enjoy heat and aroma year-round. That said, when you actually go to use them, there are often moments of doubt—“How do I make them at home?” “Do I rehydrate them before using?” “How long do they keep?”

On this page, we’ve compiled, from the standpoint of someone involved in processing dried vegetables, everything from how to make (dry) dried chili peppers, to how to rehydrate them in water and remove the seeds, uses like oil steeping and soy-sauce steeping, airtight storage and shelf life, and how to use up a large amount. It’s useful for everything from homemade batches to choosing commercial ingredients.

What Are Dried Chili Peppers? The Difference from Fresh Chilies

Dried chili peppers are ripe red chilies dried to remove their moisture. Drying raises storability and concentrates the heat and umami. First, let’s sort out the names and how to distinguish them from fresh.

The Relationship Between Dried Chili Peppers and Takanotsume

Much of what’s sold at supermarkets as “dried chili peppers” or “dried togarashi” is the takanotsume variety, dried. Takanotsume is one variety among chili peppers, and the flagship of the hot chilies. There are others used for drying, such as yatsubusa and hontaka, and some are made by drying scorching varieties like habanero—the heat and aroma differ by variety. For the full picture of the varieties, seean explanation of the kinds of chili pepper.

The Differences and Uses of Fresh, Dried, and Powdered

Fresh chilies have a juicy aroma and heat as their strength, and suit uses like a green-chili condiment. Dried, they keep well and can be used whole to flavor oil or rehydrated in water. Ground into powder, they mix evenly into dishes and are easy to use as a base for togarashi or seasonings. Even the same chili greatly broadens its uses when its form changes.

Which Suits Drying—Red or Green Chilies?

What suits drying is ripe, red chilies. Red chilies carry heat, sweetness, and aroma, and their flavor concentrates when dried. Green chilies are in an unripe green state, high in moisture with a fresh heat as their strength, so they’re more often used fresh or pickled than dried. To make dried chili peppers, choose fruit that’s turned solidly red.

At home too, if you have red chilies, you can make dried chili peppers yourself. There are several drying methods; choose to match the weather and the amount.

Choosing Between Sun-Drying and Shade-Drying

The easiest is sun-drying. On a clear, sunny day, arrange them on a colander or net so they don’t overlap and dry them in a well-ventilated spot. If harvested on the branch, you can remove the leaves and hang them under the eaves. When you want to keep the color and aroma gentle, shade-drying away from direct sunlight suits well. Either way, avoiding moisture is the tip for a nice finish.

Drying Steps and Handling the Stems and Seeds

The basic steps are as follows. Dried whole, they can be stored as is; removing the stems and seeds before drying makes them easier to use later.

1. Rinse the red chilies quickly and blot off the moisture thoroughly
2. Arrange them on a colander or net so they don’t overlap (hang branch-attached ones)
3. Dry them in a well-ventilated spot, turning them over partway through
4. Wait about two weeks of clear weather until the surface wrinkles and the whole thing dries

How to Tell When They’re Dry

When they rattle when shaken and snap crisply between your fingers, that’s the sign they’re dried through to the center. If they only bend without breaking, or feel moist when pressed, moisture still remains. Under-drying causes mold, so dry them thoroughly before moving to storage.

How to Rehydrate and Prep Dried Chili Peppers

Dried chili peppers can be used as is or rehydrated. Changing the prep to match the dish lets you adjust both heat and texture.

Steps for Rehydrating in Water

For using them whole in stir-fries and simmered dishes, you can use them as is without rehydrating. When you want to chop them and blend them into a dish, or eat them soft, soak them in warm water for about 10–15 minutes to rehydrate. The soaking liquid also carries heat and aroma, so add it to the dish rather than discarding it—nothing goes to waste.

Removing the Seeds and Adjusting the Heat

The source of the heat is largely in the white pith inside where the seeds attach. When you want to hold back the heat, cut off the stem, roll the chili lightly to shake out the seeds, then use it. Conversely, when you want the heat to hit hard, chop it up seeds and all. Being able to adjust the heat by the amount of seeds is one of the fun parts of handling dried chili peppers.

Making Them Easier to Use in Rounds or Chopped

Cutting them into rounds in advance saves the trouble of chopping every time you cook. When dry, they cut easily with kitchen scissors. Slice a batch into rounds and store them, and you can quickly add them to hot pots, udon, and stir-fries. Ground into powder, they also work as homemade ichimi.

How to Use Dried Chili Peppers, with Recipes

Dried chili peppers can be used in all sorts of dishes by changing their form—whole, chopped, or powdered. Here are representative uses, organized by form.

Flavoring Dishes Whole or in Rounds

For peperoncino or ajillo, heat them whole in oil slowly with garlic to transfer the heat and aroma into the oil. For mapo tofu or kinpira, adding rounds spreads the heat throughout. Charring them in oil brings out bitterness, so heating slowly over low heat is the tip.

Making Pantry Seasonings with Oil or Soy-Sauce Steeping

Put dry-roasted dried chili peppers in a clean jar and pour in olive oil to keep as a chili oil in your pantry. Steep them in soy sauce for a spicy seasoned soy sauce. Just adding a little of either to a dish tightens the flavor—handy for pasta, stir-fries, chilled tofu, and more.

Grinding into Ichimi or Homemade Seasonings

Grind thoroughly dried chili peppers in a mill or mortar for homemade ichimi togarashi. Combine them with sansho, sesame, and dried citrus peel and they become shichimi. The fine aroma you can’t find in store-bought is a pleasure unique to homemade. When you want to make the most of the color, using a colorful variety likePurple chili pepper powderis also recommended.

How to Store Dried Chili Peppers and Their Shelf Life

Even chilies you’ve gone to the trouble of drying lose flavor or grow mold if stored wrong. Here we’ve compiled the tips for keeping dried chili peppers in good condition for a long time.

Airtight, Refrigerated Storage

Once thoroughly dried, put them in a clean jar or zip-top bag with a food-grade desiccant, press out the air, and seal. Storing them in the fridge away from direct sunlight and moisture keeps the flavor for a long time. Absorbing moisture drains the heat and aroma and causes mold, so an airtight seal matters most of all.

A Shelf-Life Guide and How to Spot Spoilage

Dried chili peppers stored airtight at home are best used up within roughly six months to a year to keep the aroma and heat. Fading color, weakening aroma, and white powder or mold are signs the flavor has declined. For shelf-life and storage points in commercial use, seeBest-before dates and storage of commercial dried vegetablesalso explained in detail in.

How to Use Up a Large Amount

When you get your hands on a lot, processing them into rounds or powder makes them easier to use up. Oil steeping or soy-sauce steeping lets you work them into daily cooking as a seasoning. Grinding them into powder and freezing a batch keeps the aroma well and lets you take out just what you need.

Dried Chili Peppers as a Commercial and Processing Ingredient

When using dried chili peppers as an ingredient at a restaurant or in product development, choosing from a different perspective than at home leads to fewer failures. From a maker’s standpoint, we’ve organized the points for choosing.

Points for Choosing for Commercial Use

For commercial use, in addition to variety, the axes of selection are origin, degree of drying, particle size, and consistency of heat. Unlike home use, reproducibility of the finish and lot-to-lot stability are what matter, so checking the following items reduces failures.

• Whether the form (whole, rounds, powder) fits the production process
• Whether the particle size and degree of drying are consistent
• Whether the variation in heat (lot differences) is within tolerance
• Whether the growing region and variety can be identified and traced
• Whether the needed quantity can be secured from a small lot
• Whether the lead time and storage conditions (shelf life, storage temperature) fit your operation

Sticking with domestic sourcing makes the ingredient’s history easier to trace and the flavor and heat easier to manage. Imports have a price advantage but can take more effort to verify lot differences and history, so choose to suit the application.
