Broccoli Tempura

Japanese crispy broccoli florets in a featherlight tempura batter with dipping sauce

Origin: Tokyo, Japan

From the journey of Broccoli.

Tempura was introduced to Japan by Portuguese Jesuit missionaries in the 16th century and became one of the defining techniques of Japanese cuisine: a featherlight, ice-cold batter that creates a crackling, almost translucent crust around vegetables and seafood. Perfected in Edo-period Tokyo (1603–1868), tempura transformed humble street food into high art. Broccoli tempura has become a popular expression of Japan's evolving relationship with this Western vegetable, combining the ancient technique with an ingredient that only achieved national dietary staple status in the 21st century.

Ingredients

Ingredients

  • 500 g broccoli, cut into medium florets
  • vegetable oil, for deep-frying

Batter

  • 150 g plain flour
  • 50 g cornflour (cornstarch)
  • 1 egg yolk
  • 250 ml ice-cold sparkling water

Dipping Sauce

  • 200 ml dashi stock
  • 3 tbsp soy sauce
  • 2 tbsp mirin
  • 4 tbsp daikon radish, grated
  • 1 tsp fresh ginger, grated

Method

  1. Make the dipping sauce (tentsuyu): combine dashi, soy sauce, and mirin in a small pan. Bring to a simmer, then cool. Serve with grated daikon and ginger on the side for each diner to add.
  2. Heat vegetable oil in a deep, heavy pan to 175°C (350°F). Use a thermometer: temperature control is critical for tempura.
  3. Make the batter just before frying: sift flour and cornflour into a chilled bowl. Add the egg yolk and ice-cold sparkling water all at once. Mix with chopsticks using a few swift strokes: the batter should be lumpy and streaky. Do not overmix.
  4. Working in small batches, dip broccoli florets in the batter and lower gently into the oil. Fry for 2–3 minutes until the batter is pale golden and crisp.
  5. Drain on a wire rack: never on paper towels, which trap steam and create sogginess. Serve immediately with the dipping sauce.

Notes

The sparkling water and lumpy batter are not mistakes: they are essential. The carbonation and cold temperature inhibit gluten formation, and the lumps create air pockets that puff and crisp as they fry.
