Is red enchilada sauce spicy?
It can be. With just guajillo and ancho, this is usually mild to medium. If you add árbol chiles, it moves into medium-hot fast. Heat guide: 0 árbol = mild, 1 = medium, 2 = hot. My advice: start with 1 árbol, blend, taste, then decide if you want to invite more chaos.
Can I make it without flour?
Yes. Skip the roux and simmer the blended chile sauce with broth until it reduces to your preferred thickness, about 15 to 25 minutes. It will be a little lighter and less clingy, but still very good.
How do I make it gluten-free but still thick?
Easy: skip the flour roux. Simmer the sauce until slightly reduced, then whisk in a cornstarch slurry (1 tablespoon cornstarch + 1 tablespoon cold water). Simmer 1 to 2 minutes until it thickens.
Why does my sauce taste bitter?
Usually one of three things: the chiles were toasted too long (they go bitter fast), the stems were left on, or the seeds and inner ribs were left in and can contribute harshness. Fix it by stirring in a small pinch of sugar or a teaspoon of honey, plus a squeeze of lime. Taste again. If it tastes truly burnt or ashy, no amount of honey can save it, and you may need to start over with a gentler toast.
Can I use chili powder instead of dried chiles?
You can, but it will taste more like “taco night” and less like enchilada-shop depth. If you need a shortcut, use 2 to 4 tablespoons chili powder (start with 2, then add to taste), skip soaking and blending, and whisk it into the broth. Still simmer it and finish with a little acid. Note: many chili powders include salt, garlic, and cumin, so taste before adding extra seasoning.
Do I need to strain the sauce?
If your blender is strong and you soaked the chiles well, you might not need to. If you want that ultra-smooth restaurant texture, strain it through a fine-mesh sieve after blending.
My sauce is too thick or too thin. Help?
Too thick: whisk in a splash of broth or water until it loosens up.
Too thin: simmer a few minutes longer, stirring often, until it coats the back of a spoon.
