Traditional Enchilada Sauce

Why This Traditional Enchilada Sauce Works

As the oil and flour cook together, the flour browns a little and swells in the fat. That browned flour is what makes the sauce thicken later instead of staying watery. When the chili powder hits the hot pan, it wakes up in the oil and sticks to the flour, so it doesn’t taste dusty or raw.

Once the chicken broth is whisked in, the flour starts to soak it up. At first the liquid looks thin, but as it heats, the flour thickens it and the chili powder spreads evenly through the pot. Tomato paste goes in thick and stiff, but with the hot broth it loosens and blends, giving the sauce body so it clings to tortillas instead of running off.

During the simmer, the spices soften into the sauce. The sharp edges from the chili powder, cumin, and cayenne calm down, and the garlic and onion powders spread through every spoonful. By the end of the 15 minutes, the sauce has tightened up, coats a spoon, and tastes like one smooth, steady flavor instead of a bunch of separate parts.

Mistakes To Avoid

Letting the flour and oil mixture stay pale instead of cooking to a light golden color leaves the sauce with a raw flour taste and a slightly pasty feel. The roux never fully toasts, so the sauce can feel chalky on the tongue instead of smooth.

When the flour and chili powder sit too long on high heat, they can scorch on the bottom of the pan. Burned flour and spices turn the whole batch bitter and give the sauce a harsh, burnt smell that no amount of seasoning can hide.

Pouring in the chicken broth too fast causes lumps of flour to form that never fully break down. Those clumps thicken in spots while the rest of the sauce stays thin, so the texture ends up uneven with little gummy bits.

Skipping the simmer or cutting it very short keeps the tomato paste and spices from loosening and blending into the liquid. The sauce then stays sharp and thick in a heavy way, and it doesn’t cling evenly to tortillas.
