This Orange Butter Sauce is a French "Beurre Blanc" ("white butter") sauce based on a reduction of shallots and an acid such as vinegar, citrus juice, or wine, mixed in with cold butter.

Its creamy tanginess works well with mild fish such as trout, shad, or haddock.

It may also be served with any shellfish including lobster, crab, and scallops.

You'll need one large orange or two smallish oranges to have enough juice for this recipe.

    Cook until it is syrupy and almost gone.

  2. Slowly whisk in butter:

    On low heat, whisk in the butter continuously and vigorously, 1 tablespoon at a time.

    Butter is the only emulsifier for this sauce, and if you slowly add it, continuously stirring, the sauce will achieve a silky smooth texture. Do not let the sauce boil!

  3. Add salt and pepper to taste
