    Make the lemon and butter sauce: Add the wine, shallot, thyme, and lemon juice to a medium saucepan. Bring to a simmer over medium-high heat and cook until reduced by half, 10-15 minutes.

    Reduce the heat to low and stir in the heavy cream. Add the butter, a few cubes at a time, slowly whisking after each addition until melted and incorporated, 3-4 minutes total. Do not let the sauce come to a boil.

  • 4

    Season the sauce with salt and pepper then strain through a fine-mesh sieve into a medium bowl, discarding the solids. Return the strained sauce to the saucepan and keep warm until ready to serve.
