Heat the oil in a cast iron Dutch oven to 350 degrees F.
In a large bowl add flour, seasoning, buttermilk and egg. Mix well together. Add okra to mixture and coat. Using a tablespoon, scoop mixture into the hot oil. Constantly flip fritters to cook and brown evenly, about 12 to 15 minutes. Remove fritters with a slotted spoon and drain on paper towels. Place in a serving bowl or platter and serve hot.
Mix ingredients together and store in an airtight container for up to 6 months.
