Sour cream splits when exposed to boiling temperatures due to protein coagulation. Whisking the dairy into the warm broth off the heat protects the emulsion. Maintain medium heat and remove the pan immediately when bubbles form. Keeping the sauce below a boil ensures a smooth, velvety coating.
Cooking butter and flour together for one minute eliminates the raw starch flavor before the broth enters. Whisk continuously during this stage to prevent scorching at the bottom of the pan. This paste thickens the liquid into a stable sauce that clings to the rolled tortillas rather than pooling in the baking dish.
Covering the baking dish traps steam during the initial 22-minute bake to heat the filling thoroughly. Removing the foil for the final three minutes under high broil develops golden spots on the cheese. Watch the oven closely during this phase because high broil transitions from browned to burned in seconds.
