Sous Vide Halibut, White Asparagus Risotto, and Strawberry Rhubarb Compote

Strawberry and Rhubarb are a classic combination often used in sweet dishes like pies.  Here is takes on a more savory tone but still brightens up and adds color to a dish featuring another spring favorite, white asparagus.  With the rhubarb season being pretty short, I usually make a large batch of the compote and freeze it for later use.  While the process looks very long, many things can be done in parallel while ingredients steep and cook.  This dish is adapted from a recipe by the Voltaggio brothers’ cookbook VOLT ink..

White Asparagus

  • Strain the stock using a fine mesh sieve.  If making the asparagus risotto immediately, heat to just below a simmer.  Otherwise, cool completely and refrigerate until making the risotto.

  • In a small pot, combine the water, Riesling, sugar, and salt over medium high heat and bring to a simmer.
  • Cook until the liquid is reduced by a third (about 10 min)
  • Add the strawberries and bring the liquid back to a simmer.  Remove from heat, cover and let steep for 20 minutes.

Strawberry Sauce

  • Strain the syrup back into the same pot, discarding the strawberries.  Bring back to a simmer and cook until reduced to 60g (about ¼ cup).
  • If you are making the rhubarb compote immediately leave the syrup in the pot.  Otherwise it can be cooled and refrigerated for 3 days.


Rhubarb Compote

  • In a small pot, combine the strawberry syrup (from above) and the verjus.  Bring to a simmer and cook until reduced by half (about 10 min).
  • In a separate dry pan, cook the onion over low heat until it is caramelized (about 10 min).

  • Add the rice and stir to coat in the fat.  Cook stirring frequently until the rice is toasted and giving off a slightly nutty flavor (about 3 min)

White Asparagus Risotto 1

  • Add the asparagus stock one or two ladles full at a time.  Stir after each addition and cook stirring frequently until the liquid is almost evaporated before adding another ladle.

  • Adjust the heat to keep the risotto at a low simmer and keep adding the ladles of stock until it is all absorbed.
  • Add the cheese and the remaining butter and stir to incorporate thoroughly.

  • Immerse the fish in the brine and let rest in the refrigerator for 10 min
  • Removed the fish from the brine and pat dry.  Discard the brine.
