Blender Bearnaise Sauce - cooking recipe

Ingredients

2 tablespoons white wine
1 tablespoon cider vinegar
1 teaspoon dried tarragon
1/2 teaspoon dried minced onion
1/4 teaspoon ground black pepper
1/2 cup butter
3 egg yolks
2 tablespoons lemon juice
1/2 teaspoon salt
1 pinch cayenne pepper

Preparation

Combine wine, vinegar, tarragon, onion, and black pepper in a skillet; bring to a boil and cook until almost all the liquid is evaporated, 2 to 3 minutes.
Place butter in a microwave-safe bowl and heat in microwave until fully melted, 30 seconds to 1 minute.
Place tarragon mixture, egg yolks, lemon juice, salt, and cayenne pepper in a blender; pulse until combined, 5 to 10 seconds. Remove the small hole cover from lid; stream butter into egg mixture while blender is running until sauce is completely blended and smooth.
