What each ingredient does

Corn
Provides the main bulk, starch and natural sweetness of the dish.
Tartaric acid
Adds acidity, which lowers the pH of the corn.

The step that matters

Dissolving the tartaric acid fully before adding it. Acid that is not completely dissolved can settle in pockets, leaving some corn more acidic than the rest. Dissolving it in warm water first lets it spread evenly through the batch.
