Measure everything before starting. This sauce cooks fast!
Heat oil in a medium pot over medium heat. Once hot, whisk in chili powder, cumin, oregano, garlic powder, flour, salt (I use ½ tsp), and a pinch of pepper. Stir for 1–2 minutes until fragrant and darkened. Whisk in tomato paste and cook, stirring constantly, for 1 more minute.
Slowly pour in chicken broth, whisking constantly to avoid lumps. Bring to a simmer over medium-high heat, then reduce to medium-low. Cook for 5–10 minutes, stirring occasionally, until thickened.
Remove from heat. Stir in vinegar. Taste and adjust seasoning. Add sugar if it’s too spicy. Use right away or let cool and store.
