Bearnaise Sauce Ingredients

- ¼ cup of White Wine Vinegar
- ¼ cup of White Wine
- 6 whole Peppercorns
- 1 tablespoon of Onion, diced
- 3 Egg Yolks
- 9 ounces of Unsalted Butter
- ½ teaspoon of Salt
- ¼ teaspoon of Pepper, ground
- 2 tablespoons of Tarragon, finely chopped
How to Make Bearnaise Sauce

- Place a small saucepan over medium heat, add the vinegar, wine, peppercorns, and onion. Reduce until 2-3 tablespoons of liquid remain.
- Strain out the onion and peppercorns and pour the liquid into a heatproof bowl. Add the egg yolks.
- Melt the butter until the milk fat (white liquid) has separated from the yellow butter. Set aside.
- Place the bowl over a saucepan of simmering water and start whisking.
- Continue to whisk until the mixture is thick and foamy and creates thick ribbons when the whisk is lifted.
- Remove the bowl from the heat and slowly pour in the hot butter while whisking, ensuring that the milk fat is left behind. This step is similar to making mayonnaise – if you add the butter too quickly the sauce will split.
- Whisk in the salt, pepper, and tarragon.
- Serve immediately or keep warm until needed.
