Warm the tortillas first so assembly starts clean
Corn tortillas are usually the first failure point in seafood enchiladas. If they go into the filling step cold or stiff, they crack, leak, and force you to hide the damage under too much sauce.
is the most reusable lesson here. You do not need them fried crisp or dipped in a separate chile sauce first. You just need them warm enough to roll without fighting back.
Once the tortillas are flexible, the enchiladas line up faster and hold their shape better, which means you can use a more controlled amount of sauce from the start.
