Classic béarnaise is one of those sauces that feels almost impossibly luxurious, and this fennel-forward version takes it somewhere even more interesting. The aromatic reduction — built from white grape juice, water, fresh tarragon stems, and finely chopped fennel — gives the finished sauce a gentle, anise-kissed brightness that cuts through the richness of the butter beautifully. Every ingredient here is straightforward and easy to trace, which matters when you're being mindful about what goes into your food. Pasteurized egg yolks are whisked gently over a double boiler until they reach a safe internal temperature, so you get all the silky, emulsified texture of a proper French sauce without any corners cut. The butter goes in one tablespoon at a time, building that glossy, spoonable consistency that makes this kind of sauce worth the effort. A handful of freshly chopped tarragon leaves stirred in at the end keeps the herb flavor bright and clean rather than cooked-down and flat. Spoon it over grilled fish, steamed vegetables, or a simple piece of chicken and it instantly elevates the whole plate.

½ cup unsalted butter, cut into 1-tbsp pieces

Combine the white grape juice, water, chopped tarragon stems, and fennel in a small saucepan over medium heat. Bring to a simmer and cook until the liquid reduces to about 2 tablespoons, 5–7 minutes. Pour through a fine-mesh strainer into a heatproof bowl, pressing the solids to extract all the liquid; discard the solids.
