Clean the shrimp and season with 1 tbsp of cajun spice.
Drizzle the flour over the shrimp and toss in a bowl to make sure each shrimp is covered in flour.
In a deep skillet add butter and olive oil and heat over high heat. Add shrimp and cook on each side about 2 min until crisp. Remove shrimp from skillet and set aside.
