Ingredients Equipment Method Notes

Ingredients
  

  • 12 large raw prawns peeled, tails on, thoroughly dried
  • 1 cup all-purpose flour sifted
  • 2 tablespoons cornstarch for extra crunch
  • 1 pinch salt lightly seasoned
  • 1 cup ice-cold sparkling water preferably in a bottle
  • vegetable or peanut oil enough for 2-3 inches deep oil for frying
  • 1 lemon or lime fresh citrus for squeezing after frying

Equipment

  • Deep Fryer or Heavy Bottomed Pot
  • Wire rack
  • Slotted spoon
  • Mixing bowl
  • Thermometer

Method
 

  1. Gather your deep-fryer or heavy-bottomed pot, a wire rack, a slotted spoon, a mixing bowl, and a thermometer. Set everything nearby for a smooth frying process.
  2. Peel your prawns, leaving the tails on for a nice presentation, and pat them thoroughly dry with paper towels. This step helps prevent splattering and ensures crisp batter adhesion.
  3. In a mixing bowl, whisk together the sifted flour, cornstarch, and a pinch of salt. Add the ice-cold sparkling water gradually, gently folding until just combined; the batter should be lumpy and light, not smooth.
  4. Pour vegetable or peanut oil into your pot, filling it about 2-3 inches deep. Attach your thermometer and heat the oil to 180°C (350°F). Watch for the oil shimmering and a slight ripple effect.
  5. Once the oil reaches the right temperature, gently dip a prawn into the batter, letting excess drip off, then carefully lower it into the hot oil using a slotted spoon. Fry in small batches to avoid overcrowding.
  6. Listen for a lively crackling sound as the prawn hits the oil. Fry for 2-3 minutes, turning gently if needed, until the batter turns a light golden and puffs up slightly.
  7. Use the slotted spoon to lift the prawns out, letting excess oil drain, then transfer to the wire rack. Repeat with remaining prawns, maintaining the oil temperature.
  8. Squeeze fresh lemon or lime over the crispy prawns to add brightness. Serve immediately while the batter is still crisp and tender inside.

Notes

For extra crispiness, use rice flour or a mix of rice and wheat flour. Maintain steady oil temperature and fry in small batches for the best crunch. Serve hot for maximum texture and flavor.
