How do I make hot sauce from dried chiles or chipotles?

To make sauce from dried chiles, stem and seed the pods, toast them briefly in a dry pan until fragrant, soak them in boiling water or broth for 15 to 30 minutes until soft [1], then blend with fresh liquid, vinegar and seasonings. Soaking longer than 30 minutes can weaken the flavor, and the soaking water can taste bitter, which is why New Mexico State's preservers discard it [1]. Dried chiles have lost most of their water, so the sauce needs more added liquid than a fresh-pepper recipe. Chipotle is a smoked jalapeño [2]. This page gives the method, how to record the liquid, the chipotle forms, and the safety points specific to dried chiles.

What changes when the pepper is dry

No tested recipe for a dried-chile hot sauce was found, so the method on this page is the usual kitchen practice, and the sauce it makes is untested and refrigerator-only.

Three differences shape every step that follows.

• Water. Dried chiles are held at about 10 to 15 percent moisture [3]. You are adding that water back, plus the liquid the sauce needs.
• Concentration. Flavor, color and heat are packed into less weight. Gram for gram, a dried pod brings far more of all three than a fresh one.
• Raw material risk. Drying stops growth but does not reliably kill microbes; Salmonella can survive in dried foods [1]. A dried-chile sauce still needs a cook step and enough acid, like any other sauce.

Making a dried chile sauce, step by step

What you need

• Dried chiles, weighed.
• Boiling water or broth for soaking.
• Vinegar of 5 percent acidity, the strength tested preserving recipes call for [6], salt, and any aromatics in your recipe.
• A dry skillet, a bowl, a plate to weigh the chiles down, a blender, a fine strainer, and a kitchen scale.

Steps

1. Inspect. Discard any pod with mold, a musty smell or insect damage. Never use pods from a decorative ristra; lacquered ristras are not safe to eat [4].
2. Stem and seed. Wear gloves. Snap off the stems, split the pods and shake or scrape out the seeds and pale ribs. The ribs hold much of the heat, so keep some if you want it hot; see where the heat comes from.
3. Toast. Press the flattened pods onto a dry skillet over medium heat for a few seconds per side, just until they soften, darken slightly and smell toasty. Burned spots turn bitter. Pull them off before they smoke. Toasting is optional; it deepens flavor and is worth trying side by side once.
4. Weigh the toasted pods. Write the weight down. You will need it in step 6.
5. Soak. Put the chiles in a bowl, cover with boiling water or broth, and weigh them down with a plate so they stay submerged. Stir occasionally. Soak 15 to 30 minutes, until soft; thin pods soften faster than thick ones, and soaking longer than 30 minutes can weaken flavor [1].
6. Drain and weigh again. The gain in weight is the water the chiles absorbed. Decide on the soaking liquid (next section).
7. Blend. Blend the soaked chiles with fresh water or broth, vinegar, salt and aromatics. Add liquid a little at a time until the blend moves freely, and weigh every addition.
8. Strain. Dried chile skins rarely break down fully. Press the purée through a fine strainer for a smooth sauce, scraping the underside.
9. Cook. Simmer the strained sauce. This is also when you adjust thickness by reduction; weigh the pot before and after so you know the finished weight.
10. Refrigerate it. This is an untested sauce, so it goes in the refrigerator whatever its pH. Measure the pH if you want to know where it landed; what the number means is on what pH hot sauce needs to be.

The soaking liquid: keep it or pour it off

This is the most common question about dried chile sauces, and the sources and the cooks disagree.

A gentle toast and a soak inside the 15 to 30 minute window keep the most flavor in the chiles [1]. Taste the liquid every time before you decide. Whatever you choose, write it in your recipe and do the same every batch.

How much liquid dried chiles need

A fresh-pepper recipe gets much of its liquid from the peppers themselves. A dried chile sauce has to add it. The way to make your own sauce repeatable is to record every line by weight as you go:

The amounts are yours to find; no tested proportions exist for this kind of sauce. Once you have recorded them, you can repeat the sauce exactly. If you want a thicker or thinner result, change the added liquid or the simmer, as described on getting the thickness right.

If you are converting a fresh-pepper recipe to dried, do not swap weight for weight. Start with a small test batch, add liquid until the texture matches, and taste for heat; the dried chiles will usually bring much more per gram.

Chipotle and other smoked chiles

Chipotle is jalapeño that has been smoked and dried [2]. Smoke changes the flavor and darkens the color. The USDA's commercial specification for hot sauce lists chipotle peppers as a standard ingredient and gives a chipotle sauce type, described as dark brownish-red, at 1,500 to 2,500 Scoville Heat Units with a pH of 2.9 to 3.2 [5]. That is a useful benchmark for color, acidity and heat if you want a commercial-style chipotle sauce.

Smoked chiles go well with dried red chiles such as New Mexico types or pasilla, which add body and color without much more heat. Published heat ranges for those are on hot sauce peppers by flavor and heat.

Using chile powder in a sauce

Powder is the fastest dried form to use and the easiest to overdo.

• Hydrate it. Whisk powder into the liquid, not the other way round, and let it stand a few minutes before you judge thickness. Powder keeps absorbing liquid.
• Cook it. Powders are raw dried products, and Salmonella can survive in dried foods [1]. Simmer any sauce made with powder rather than stirring powder into a finished, cold sauce.
• Taste for grit. Coarse powder leaves a sandy feel. Strain, or blend longer.
• Buy fresh, store dark. Dried peppers fade quickly in light [6], and powder has more surface exposed. Store it airtight and dark and use it within the time on the package or within months of opening.

Safety points specific to dried chiles

• Rehydrated chiles are a low-acid vegetable again. Once soaked, they behave like fresh peppers for food safety. The sauce needs enough acid, a cook step, and refrigeration unless it follows a tested canning recipe or a scheduled process.
• Do not hold soaked chiles at room temperature. Blend and cook the same day, or refrigerate them.
• Never store soaked or fresh chiles in oil at room temperature. Low-acid plant material in oil is a classic botulism risk. Oil products are covered on chili oil and chili crisp.
• Discard moldy pods. Do not wash or toast them and use them. More on mold is on storing peppers until you make sauce.

Getting a deep red or brown color to hold

Dried and smoked chiles give sauces a color fresh peppers cannot, and that color can still drift darker over time in the bottle. Why sauces brown, and what you can control, is on keeping the color in your sauce. If you would rather start with fresh peppers and a tested recipe, see a simple vinegar hot sauce from a tested recipe.
