Poisson au beurre blanc et rouge (Poached Fish with White and Red Butter Sauce)
Beurre blanc (burr BLAHN or burr BLAHNGK), which means "white butter", is a classic French sauce that turns half a pound of butter into something "light" and delicious. It's similar to Béarnaise sauce {without the tarragon or eggs} since it's a reduction of vinegar or white wine and shallots into which butter is whisked in, but it's a little easier since no eggs are involved. Again, we're emulsifying this week!
This recipe called for brochet, or pike. The River Loire, which is the longest in France, is home to numerous fish, including pike. Unfortunately, the Loire River is too far from Ottawa and pike was not to be had. After seeing numerous recipes with beurre blanc over a variety of fish, I decided to go with our favourite — Salmon with a beurre blanc — and for a color difference — Sea Bass with a beurre rouge.
A bit of history
There is some controversy about the history of beurre blanc. One theory is that the Anjou region is the birthplace of this sauce...

Beurre blanc is delicate, light, and full of fat! But it's so much easier than making a Béarnaise...

{Confession time: Although I should have practiced my fish filleting, I chose the easy route and bought fillets ready to poach. I did, however, buy a trout that needs knife attention and will give that a go sometime this week.}
A bit of history
There is some controversy about the history of beurre blanc. One theory is that the Anjou region is the birthplace of this sauce and that it was first served at the restaurant "La Poissonnière" in Anger. The more popular theory is that around the beginning of the 20th century, a cook named Clémence Lefeuvre served this sauce at her restaurant "La Buvette de la Marine" on the banks of the Loire River near Nantes. The legend says that she meant to make a Béarnaise sauce but forgot to add the tarragon and egg yolks.
A bit of butter Beurre blanc is mostly butter, so it's important to use one you like. No margarine allowed! Jean-Yves Bordier makes the "best butter in all of France”. He comes highly recommended by many foodies, including Clotilde Dusoulier and David Lebovitz.
Since Bordier's butter isn't imported to any stores in Ottawa, I decided to try my own taste test and gathered up all the varieties of butter I could find in the Byward Market in Ottawa. I found seven varieties: three unsalted and four salted. Then, at home, we enjoyed a taste test. {Have you ever tasted seven different butters at one sitting?!}
I was amazed to find each one had its own distinct flavor and qualities. One tasted acidic, another nutty, one was bland, another rich. There was also no agreeing on which one was best, so I made the executive decision as the "chef" and picked my favorite unsalted one to use in the beurre blanc sauce (Saputo Unsalted at $5.99 a pound, which is $1.50 more than the brand I usually buy!). "It was the best butter,” the March Hare meekly replied — Lewis Carroll
A bit of cream…or not
Traditional beurre blanc doesn't include cream, but many recipes (including the one in Le Cordon Bleu at Home which uses crème fraiche) include it to help stabilize the sauce and guard against the sauce breaking. The cream provides more emulsifying power. {You can find out more great science facts behind this sauce in Cookwise by Shirley O. Corriher.}
If cream is added, the sauce is called Beurre Nantais.
I made both a beurre blanc using white wine and white-wine vinegar and a beurre rouge using red wine and red-wine vinegar. The pink salmon had the the beurre blanc, and the white sea bass was ladled with beurre rouge.

For the beurre blanc, I used Muscadet (Muss-ka-day), which means "wine with a musk-like taste", and it's the wine usually used in this sauce. It's a dry French white wine made in the Loire Valley near the city of Nantes that uses the Melon de Bourgogne grape varietal. I was able to find a good bottle of Muscadet at a reasonable price at my local wine store."[Muscadet is] the best wine ever made for seafood”
"Le vin est la plus saine des boissons."
"Wine can be considered with good reason as the most healthful
and the most hygienic of all beverages."
— Louis Pasteur (printed on the cork of the Muscadet)
The first step in making beurre blanc is reducing the shallots, wine, vinegar, thyme and bay leaf until it's a syrupy glaze. Once you have the glaze, let this mixture cool for a bit and remove the thyme sprig and bay leaf. [If called for in the recipe, add the cream or crème fraiche. I used cream since I didn't have any crème fraiche.] Then slowly whisk in the softened butter, a bit at a time. Whisk constantly. Take the pan on and off the heat to whisk in the butter without melting it. Make sure you don't let the mixture boil or it will separate, and it cannot be re-emulsified at this point. Taste. Add salt. Taste. Add more butter if it's too acidic. Taste.
The sauce will separate above 58ºC (136ºF) and solidify below 30ºC (86ºF).
Traditionally, the sauce is not strained. If the shallot is chopped fine enough, it doesn't distract from the texture of the sauce.
Beurre blanc is best served immediately, but can be held in a thermos or over a simmering water bath. If re-heated, it will break easily. Since it doesn't contain eggs there isn't the same worry of bacteria growth that you have with Béarnaise and Hollandaise.
To save time if you're entertaining, you can prepare the reduction of shallots, wine, vinegar, thyme, and bay leaf ahead of time and whisk in the butter just prior to serving.
A bit of variety
To change the taste of beurre blanc, you can use all sorts of different flavors in the reduction or whisk in one of the compound butters mentioned last week instead of plain unsalted butter. I used the Maître d'Hôtel compound butter in a third version that I made, which definitely gave it a flavor boost. Here are some other ideas for flavoring beurre blanc.
A bit of entertainment
Here's a great video showing how to make beurre blanc.
A bit of fish poaching
To cook the fish, the recipe calls for a court bouillon, which is a fancy name for cooking broth. After you've brought the broth ingredients to a boil and simmered them for about 15 minutes to marry the flavors, you let the mixture cool a bit before adding the fish. {I threw the pot into the refrigerator to speed up the process since I was running behind.} Add enough water to cover the fish, put the lid on and bring to a boil. Remove the pot from the heat and let cook for about 30 minutes, covered. Pretty simple.

Beurre blanc is delicate, light, and full of fat! But it's so much easier than making a Béarnaise. I enjoyed the beurre blanc made with the compound butter, but my husband liked the beurre rouge best. These sauces definitely make plain, old, boring fish more delicious to eat! Too bad about the calories!
