Which three parishes are named for the lower and middle Bayou Teche Cajun food region?

The lower and middle Bayou Teche Cajun food region is named for Iberia, St. Martin, and St. Mary parishes.

Bayou Teche is a major waterway in south-central Louisiana, running through the heart of Acadiana. Its surrounding landscape combines fertile floodplains, lakes, streams, and bayous. That environment supported both hog farming on the prairies and seafood gathering in the wetter lowlands.

The region is a culinary meeting ground rather than a sharply isolated food zone. Cooking traditions from the western prairies overlap there with those of southeastern Louisiana's Bayou country. Seasoning practices likewise occupy a middle position: cooks use more cayenne than many Bayou communities, but the food is not identical to the heavily pepper-oriented cuisine of the Cajun prairies.

This geography also explains why the region can be confused with broader Acadiana or with neighboring parishes. Bayou Teche itself extends through additional areas, including St. Landry Parish, but the named lower-and-middle food region specifically refers to Iberia, St. Martin, and St. Mary.
