Toast the dried oregano and cumin in the hot oil for 30 seconds before adding flour to release their essential oils and deepen their flavors exponentially.

Cook the flour and oil together for 1-2 minutes, stirring constantly, to create a smooth paste that prevents lumps when you add the liquid and ensures a silky sauce texture.

Add the vegetable broth slowly while whisking continuously to avoid lumps; pour in a steady stream while maintaining vigorous whisking for a perfectly smooth, lump-free sauce.

Start with equal parts sweet and hot paprika, then adjust to your heat preference after tasting; this creates complexity rather than just one-note spice heat.

Let the sauce bubble gently for 3-4 minutes after combining all ingredients to allow flavors to meld and reduce slightly, intensifying the overall taste profile significantly.
