How to make it
1
Cut the nanohana
- Wash the nanohana
- On the cutting board, cut 1 cm off the hard ends of the stems
- Cut them in half and keep the stem halves and flower halves separate
How to tell it's doneThe stems and flowers are in 2 separate piles.
2
Boil in salted water
- Put about 1.5 L water in a pot, bring to a boil over high heat and add 2 tsp salt
- Save just 1 tbsp of the boiling water in a small bowl (you will use it in step 4)
- Add the stem halves first and boil for 30 sec
- Add the flower halves too and boil 1 min more
How to tell it's doneThe stems are bright green and bend a little when you pick them up with cooking chopsticks.
Be carefulIf you boil them too long, they lose their color and go limp. Time it.
3
Cool in cold water and squeeze out the water
- Drain the nanohana in a colander and put them right away into a bowl of water to cool
- When cool, line up the stem ends and squeeze lightly with both hands to get the water out
- On the cutting board, cut into 3–4 cm lengths and squeeze lightly once more
How to tell it's doneNo water drips when you squeeze.
Be carefulWhen pouring the water into the colander, keep your face away so the steam does not burn you.
4
Toss with mustard soy sauce
- Dissolve 1/4 tsp dashi granules in the 1 tbsp of boiling water you saved in step 2
- In a bowl, mix the dissolved dashi, 1 tbsp soy sauce and 1/2 tsp karashi (Japanese mustard paste)
- Add the nanohana, toss everything, and put in a dish
ReadyThe mustard is mixed in all over, with no lumps left. Keep in the fridge and finish by the next day.
