A classic sauce takes on a fresh twist with passion fruit, giving Passion Fruit Sauce a smooth, buttery texture with a light tang.
Place the crushed peppercorns, vinegar, wine, eschalots, tarragon, and chervil in a small pan. Bring to a boil over high heat, then boil uncovered for about 5 minutes or until the liquid reduces by half. You should have about 2 tablespoons left.
Whisk the egg yolk mixture until combined. Place the bowl over a saucepan of barely simmering water to create a double boiler. Whisk constantly for 5 to 7 minutes, until the mixture thickens and forms a ribbon that holds its shape when lifted.
Note: The bowl should feel warm, not hot. If it starts to overheat, lift it off the pan briefly, then return it.
Béarnaise sauce is best served warm, as this keeps the texture smooth and prevents it from thickening too much.
