Make the crispy prawns: Line a baking tray with parchment paper and set aside. Add the prawns or shrimp to a bowl and season with the salt, black pepper, garlic granules, onion granules, paprika and cayenne pepper then rub the seasonings into the prawns. Add in the 1 tablespoon of plain flour and also rub it into the prawns. Set the prawns aside.
To another bowl, add the 70g flour and cornflour, mix and also set aside. To another bowl, add in the egg, mustard and hot sauce then mix them together.
Take a prawn and dip it into the egg ensuring it gets fully coated. Drain off any excess egg then dip it into the flour and turn a few times to fully coat. Once fully coated, place it on the baking tray. Repeat this process with the rest of the prawns then allow the prawns to sit at room temperature for 10 minutes.
Place a large heavy duty pan or skillet on a medium to high heat and pour in the oil. Allow the oil to heat until slightly sizzling then place the prawns into the pan. Cook for 2 – 3 minutes then turn the prawns and cook for another 2 – 3 minutes. Cook until golden brown and cooked through. Remove the prawns with a slotted spoon and place on some kitchen towel to absorb the excess oil.
Make the sauce: Add the butter, hot sauce, honey, lime and chilli flakes to a small saucepan and place on a medium to high heat. Stir the mixture while the butter melts then allow the sauce to heat until the it begins to bubble. Once bubbling, allow the sauce to remain on the heat for a further minute until it slightly thickens.
Remove the sauce from the heat and set aside for a minute to slightly cool. Place the prawns on a serving plate then drizzle with the hot honey sauce. Allow to sit for 10 minutes then serve.
