Step 1

Heat a saucepan on medium heat and roast the black peppercorns and sichuan peppercorns together for 1-2 minutes until you can smell the aroma from the peppercorns. Allow them to cool.

Step 2

Add salt and sugar, and using a mortar and pestle, crush the spices together to form a coarse powder.

Step 3

Place shrimp in a large bowl. Add the spices, rice flour and oil, and mix well until the shrimp are well-coated.

Step 4

Place the shrimp in the airfryer basket, trying to keep them in as flat a layer as possible. You may want to use a rack, and place half the shrimp in the basket and the other half on the rack.

Step 5

Spray well with additional oil.

Step 6

Set the air fryer to 325F and cook for 8-10 minutes, tossing halfway through.
