Method to make Tempura Marsh Samphire:

  1. Rinse well and pat dry with a paper towel. Trim any tough ends, but keep the Samphire whole for visual appeal and ease of frying.
  2. In a bowl, mix the flour and sparkling water gently—don’t over-mix; lumps are fine. The batter should be light and slightly runny. Place the bowl in the fridge if not using immediately.
  3. Fill a small saucepan or deep frying pan with oil to about 2–3 cm deep. Heat to 170–180°C (or until a drop of batter sizzles on contact).
  4. Lightly coat the Marsh Samphire in a bit of flour. Then dip into the batter, shaking off any excess.
  5. Carefully place the Marsh Samphire into the hot oil and fry for 1–2 minutes until crisp and pale golden. Avoid overcrowding the pan. Drain on kitchen paper.
  6. Mix soy sauce, lime juice, and sweetener (if using). Add chilli flakes or grated ginger for a kick.
  7. Serve hot with the dipping sauce on the side. Best enjoyed immediately while still crisp.
