A modern sauce Normande is based on modern fish velouté, fish stock that has been thickened with hydrocolloids such as xanthan gum, guar gum, and/or lambda carrageenan. Cream is added to the sauce and it is thickened in the classic way, with egg yolks.
Combine the velouté, mussel cooking liquid, mushroom cooking liquid, and cream and bring to a simmer. Whisk together the egg yolks and whisk in half the hot liquid. Whisk thoroughly and return to the stove over low heat. Stir until thickened in the manner of a crème anglaise. Whisk in the butter. Season with salt and pepper.
