  • sourdough starter 200g
  • sparkling water 50-100ml, cold
  • long-stemmed broccoli, asparagus tips, green beans a handful of each, cut into bite-sized pieces
  • vegetable oil for frying
  • soy sauce to serve


  • Step 1

    Whisk together the starter with enough sparkling water to make a light, thin batter – a good way of testing the consistency is to dip your finger in and you should just be able to see your nail through it.

  • Step 2

    Fill a pan no more than a third full with oil and heat to 180C or until a cube of bread browns in 30 seconds. Dip a few of the vegetables into the batter, quickly whip out and add carefully to the oil. Cook, in batches, for 1-2 minutes or until golden, light and crisp. Drain on kitchen paper and season with sea salt flakes.

  • Step 3

    Continue with the remaining vegetables and batter. Serve with soy sauce for dipping.
