Fix Broken Aioli Hollandaise Bernaise Or Other Sauce Recipes

Steps:

• Put egg yolk in a clean bowl.
• Whisk it then add the broken sauce drop by drop with continuing to whisk. If you don't have 3 hands or a way to hold the bowl still, you may want someone to help you.
• Whisk until the sauce is creamy and homogeneous.
• Thin as needed with a splash of water.

Steps:

• Place butter in a medium glass bowl, and melt in the microwave, about 30 seconds on High. Whisk in the onion, white wine vinegar, egg yolks, heavy cream and lemon juice. Season with tarragon, parsley, salt, mustard powder and cayenne pepper; mix well.
• Return to the microwave, and cook for 1 1/2 minutes, or until thickened, stirring until smooth every 20 to 30 seconds.

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.
