- Polenta not labeled gluten-free (milled where wheat is handled)
- Flour-dusted polenta before frying
- Restaurant polenta fries in shared fryers
Grits
Yes. Grits are made from corn and are naturally gluten-free, though check instant/flavored versions and watch for cross-contamination.
Watch out for:
- Instant/flavored grits may add wheat-based seasonings
- Shared equipment cross-contamination with wheat
- Restaurant add-ins (e.g., flour-thickened gravy)
