In a large plastic storage bag, toss together flour, cornstarch, salt, Creole or seafood seasoning, garlic, lemon pepper, onion powder and cumin. Seal bag and shake until seasonings are evenly distributed.
Add shrimp to the bag. Seal the bag and toss the shrimp until they're evenly coated. Set the bag into fridge with the top open for 30 minutes. Repeat the process, after 15 minutes of chill time sealing the bag and shaking the shrimp. Return to the refrigerator with the top open.
Heat oil to 350-360°F. Remove shrimp from refrigerator. Seal the bag and shake again to coat.
Fry shrimp in batches for 2-3 minutes until golden turning as needed, for even browning. Have nearby a pan lined with paper towels. Remove with a slotted spoon to drain on the pan. Season with additional seafood or Creole seasoning immediately.
Meanwhile, in a small saucepan, melt together hot sauce, butter, cayenne, garlic and Worcestershire sauce. Keep warm.
After all of the shrimp is cooked, toss in the buffalo sauce.
Serve immediately with blue cheese dressing or ranch dressing and a side of carrot sticks and celery sticks.
