Visual cues dictate doneness entirely when making rolled corn or flour tortillas, as internal temperature probes are structurally impractical here. Sweet potatoes cubed to precisely one-half inch require seventeen to twenty minutes at 400 degrees Fahrenheit to achieve fork-tenderness, yielding before releasing their starches into the roast. Roasting them past this window creates a purée rather than distinct pockets of texture inside the filling. Simmering the black beans alongside their canning liquid reduces excess moisture that would otherwise steam the interior of the tortilla from within, rendering the outer roll soggy instead of shatteringly crisp.
Rolling requires tightness; loose cylinders trap steam during the second bake at 425 degrees Fahrenheit. Spreading two to three tablespoons of filling down the center establishes the correct physical diameter for a fifteen-minute high-heat finish. Generous oil coverage on the exterior acts as a thermal conductor, frying the exterior surface directly on the sheet pan. Olive oil works effectively, though refined avocado oil provides a higher smoke point if the oven runs hot.
Blending the avocado sauce in a food processor incorporates air rapidly, emulsifying the dairy and fruit fats into a stable coating without separation. Storing leftover rolled taquitos uncooked in the refrigerator for up to twenty-four hours remains viable if the tortillas are completely dry before assembly, preventing moisture degradation prior to baking.
