Spring Asparagus with Pea Flowers and Frozen Radish

1. 1
   Prepare a bath of heavily iced water in a bowl.
2. 2
   With a sharp paring knife, starting just below the head of the asparagus, peel the outer layer of fiber off each piece. It is important to peel in one motion from top to bottom, ensuring you do not peel too deeply or scratch the stems.
3. 3
   Blanch the peeled asparagus spears in boiling salted water with a ratio of 2 teaspoons salt per about 1 quart of water. Refresh the spears in the heavily iced water. The asparagus should be just cooked with a little crunch.
4. 4
   Once completely cold, remove the asparagus from the ice bath, dry, and trim the woody end from each piece. Season with a little salt and lemon-infused olive oil, and store, covered, until ready to serve.

For the pistachio purée:

1. 1
   Combine the pistachios with the olive oil and place the mixture in a Pacojet canister. Freeze the pistachios, then Pacotize to a smooth paste.

For the chlorophyll and pistachio:

1. 1
   Wash the spinach and process it in a juicer. Place the spinach juice in a saucepan and heat it, stirring constantly, to a temperature of 158 degrees Fahrenheit. At this temperature, the solid chlorophyll will separate from the water in the spinach juice. Pass the juice through a fine-mesh sieve, discarding the liquid and keeping the solid chlorophyll left in the strainer. If the chlorophyll is still quite moist, spread on paper towels to dry. You will need 10 teaspoons of the spinach chlorophyll.
2. 2
   Combine the 10 teaspoons of chlorophyll with 5 teaspoons of the pistachio purée, then add the sansho powder and a little olive oil. Season to taste. Store in an airtight container until needed, up to 2 days.

For the frozen radish:

1. 1
   Individually juice the vegetables, and pass each individual juice through a fine-mesh sieve. Combine 1 1/4 cups of the daikon juice with 3/4 cup of the fennel juice and 7 tablespoons of the cucumber juice, then add the mirin and salt. Freeze this mixture to at least -4 degrees Fahrenheit, then pass the ice through a mouli grater (or grate on a Microplane) to achieve a granita texture. Fold the julienned lovage leaves into the mixture and fluff with a fork. Reserve, frozen, until needed.

For the pea and radish flowers:

1. 1
   Using scissors, cut the flowers from their respective plants. Wash the flowers quickly in iced water, taking special care not to damage the fragile petals on the radish flowers. Pat each flower dry with paper towels and store, refrigerated, in airtight containers until needed.

To serve:

1. 1
   On each of 4 plates, drag a tablespoonful of the chlorophyll-pistachio mixture down the middle, then sprinkle a little sansho powder over top. Lay 1 asparagus spear down the right side of the purée and scatter 8 of each kind of flower to the left. Sprinkle some freeze-dried sake powder over the asparagus and drizzle a little lemon-infused olive oil over the plate and other ingredients. Add a large spoonful of the frozen radish to the right of the asparagus and serve.
