Sous Vide Sauces: Beurre Monté/Beurre Blanc

Procedure:

Make the clarified Sous-jus. This is explained in detail HERE.

Put the butter and the sous-jus in a Ziploc quart bag. It is not necessary to seal the bag, but it is acceptable to do so.

Lower the bag into your sous vide bath set @

135F/74C.

Allow 1/2 hour for the butter to become fully melted.

Remove from bath and pour butter mixture into a tall, clear, 16oz./450ml glass that the stick blender just fits into the bottom. This is important in order to create the correct amount of localized friction.

Lower the stick blender into the glass, and let the liquids settle. It is essential that the water based products accumulate in the bottom, and the oil hovers above.

Slowly begin to pulse the stick blender.

DO NOT LIFT IT UP

Again, this is essential in order to maximize friction in the bottom of the glass. Continue to pulse, and you will see the liquids begin to emulsify. There is a short accompanying video HERE.

Continue pulsing, and slowly TILT the stick blender to pull more oil down into the sauce. A little oil will always remain on the top, and it can be stirred in with a spoon. Even at this point, running the stick blender in the top of the sauce may still undo the emulsion!

 

 

Info

Sous vide products benefit from sauces just like any other! Here is an adaptation of the classic nouvelle contribution to modern cuisine!

You will need a generic stick blender for this recipe. Emulsion sauces are not nearly as difficult to make as some would have us believe. Once one understands the basic principles of dispersion, temperature, and localized friction, they can be applied equally to all emulsion sauces, be they hot or cold.

Once the method of this sauce is learned, ingredients like white wine, lemon, garlic, and other popular flavors can be added. The balance of oil base and water base must not be altered, so watch for upcoming variants of this formula in the recipe section!

Ingredients

Butter, cold, 8 oz./225g.
Clarified Sous-Jus, 1 oz./30ml
Salt to taste
White pepper, to taste.

  • Would there be any advantage to placing the correct-for-the-stick-blender container in the sousvide instead of using a plastic bag? It seems to me that by using just the container, you would disturb the layers even less? Since the bag doesn’t have to be sealed, you would just have to make sure your container didn’t tip over. Or am I delusional? I’m not a chef, just an enthusiast.
