Christina's Notes
Avoid Watery Salad: Pat dry the corn to absorb any excess moisture. Extra wetness can thin down the creamy dressing.
Char in Batches: Char the corn a little at a time so that every piece has a chance to get nice and brown.
Serve Cooled: Salad that came straight out of the fridge can have muted flavors. Let it sit at room temperature for a few minutes so the flavors can come back to life.
