BéARNAISE SAUCE

Steps:

• Melt 1 tablespoon butter in a small saucepan over medium heat. Add shallots and a pinch of salt and pepper; stir to coat. Stir in vinegar, reduce heat to medium-low, and cook until vinegar is evaporated, 3-4 minutes. Reduce heat to low and continue cooking shallots, stirring frequently, until tender and translucent, about 5 minutes longer. Transfer shallot reduction to a small bowl and let cool completely.
• Meanwhile, fill a blender with hot water to warm it; set aside. Melt remaining 1 cup butter in a small saucepan over medium heat until butter is foamy. Transfer butter to a measuring cup.
• Drain blender and dry well. Combine egg yolks, lemon juice, and 1 tablespoon water in warm, dry blender. Purée mixture until smooth. Remove lid insert. With blender running, slowly pour in hot butter in a thin stream of droplets, discarding milk solids at bottom of measuring cup. Continue blending until a smooth, creamy sauce forms, 2-3 minutes. Pour sauce into a medium bowl. Stir in shallot reduction and tarragon and season to taste with salt, pepper, and more lemon juice, if desired. DO AHEAD: Can be made 1 hour ahead. Cover and let stand at room temperature.

BéARNAISE SAUCE

Steps:

• Put the vinegar, shallots, black pepper and 1 tablespoon of tarragon leaves into a small saucepan, and set over a medium flame. Bring just to a boil, and then reduce heat to a simmer until there are only a few tablespoons of liquid left, approximately 5 minutes. Remove from heat, and set aside to cool.
• Fill a small saucepan with an inch or two of water, and set over medium-high heat to boil.
• Put the cooled shallot-and-tarragon mixture into a metal mixing bowl along with a tablespoon of water and the egg yolks, then whisk to combine.
• Turn the heat under the saucepan of water down to its lowest setting, and put the bowl on top of the pan, making sure that it does not touch the water directly. Continue to whisk the yolks until they thicken, approximately 5 to 7 minutes. You should just about double the volume of the yolks.
• Slowly beat in the butter, a tablespoon or two at a time, whisking slowly to combine and emulsify. Remove the bowl from the pan occasionally, so as not to overcook the eggs, and taste the sauce. Season with salt. If the flavor is not sharp enough, add a splash of lemon juice. If the sauce is too thick, stir in a splash of hot water. Add the remaining teaspoon of tarragon leaves, and serve.
