The final pitfall occurs after the waffle leaves the iron. Setting a hot waffle on a flat ceramic plate or stacking multiple waffles creates a thermal trap. The bottom face of the waffle radiates heat onto the cold plate, creating rapid condensation that soaks the underside in seconds.
The cooling rack trick resolves this issue. Place an elevated stainless steel wire baking rack set inside a rimmed sheet pan directly into an oven preheated to 200°F. Transfer every freshly baked waffle directly onto this wire rack in a single layer. Air circulates freely above and below the grid pockets, venting any residual surface moisture while keeping the exterior crackling hot until the entire batch is ready to serve.
