Frequently Asked Questions

Is corn meal naturally gluten-free or could it have cross-contamination?

Pure cornmeal is naturally gluten-free, but cross-contamination can occur during processing if the same facility also processes wheat products. To ensure gluten-free cornmeal, look for products specifically labeled as gluten-free.

How can I tell if a corn meal product is processed in a facility that also processes wheat?

Check the product label for allergen warnings that say “Made in a facility that also processes wheat” or “May contain wheat.” Contact the manufacturer directly if the label doesn’t provide this information.

Does stone-ground corn meal have a higher risk of gluten contamination than regular corn meal?

Stone-ground cornmeal typically has a higher risk of gluten contamination because traditional stone mills often process wheat and other gluten-containing grains on the same equipment. Regular commercial cornmeal is usually processed in dedicated corn-only facilities, making cross-contamination less likely.

Can I use corn meal as a direct substitute for wheat flour in all my gluten-free recipes?

Cornmeal cannot be used as a direct 1:1 substitute for wheat flour as it lacks gluten and has different protein content and absorption properties. For best results in gluten-free baking, use cornmeal as part of a blend with other gluten-free flours and add xanthan gum or another binder.

Are there any brands of corn meal that are certified gluten-free that you recommend?

Bob’s Red Mill and Arrowhead Mills both offer certified gluten-free cornmeal that are reliable and widely available.
