Cornmeal
This is what sets chess pie apart from other custard-filled desserts.
As the pie bakes, the cornmeal in the filling rises to the top, creating a thin, golden, and crumbly crust.
Any type of cornmeal will work, but the most common choice is stone-ground.
You can also use white cornmeal if you don’t like the corn flavor as much. White cornmeal has a more subtle corn flavor than other types.
Vinegar
Just a small touch to give the sweet pie a bit of tangy flavor contrast.
