Hollandaise sauce
This week it's Hollandaise sauce, another of the five mother sauces. (Velouté, Espagnole, Béchamel, and Tomato are the others.) Hollandaise is similar to mayonnaise and lemon curd, but it's served warm.

Hollandaise is basically a sabayon, which is a foamy, emulsified mixture of yolks and liquid (in this case water). If you were to add sugar and a sweet wine, you would have zabaglione. But, today we're adding a ton (only half a pound) of butter to the sabayon.

History and Tips
Hollandaise dates back to the 17th century and used to be named Sauce Isigny, which is a town in Normandy famous for its butter. However, during World War I, France could no longer produce butter so they imported it from Holland and the name stuck. (from Linda Stradley at What's Cooking America)

Hollandaise is a tricky beast and requires constant attention, sorta like kids. You must whisk constantly to ensure the eggs don't stick to the bottom of the pan and to keep the texture smooth, not grainy.

There are different ways of making hollandaise: with a double boiler or directly over the flame. With clarified butter or with cubes of unsalted butter. With a blender or just a whisk.

Today, I tried putting the yolks directly over the flame (or burner, in my case!) and whisked constantly. I also made two batches: one using clarified butter and the other using butter cubes. The sauce with the clarified butter was runnier, plus I prefer the flavor from using the milk solids from good 'ol butter (and I'm not wasting any precious butter).

Earlier this year, I made lemon curd for a lemon cream tart and at the same time tried making a hollandaise sauce following the method suggested for Dorie's The Most Extraordinary French Lemon Cream Tart. It turned out great. This is yet another option for making hollandaise.

Hollandaise Trouble
Many things can go wrong with this sauce, but here are the tips I found to try to correct the problem.

• If curdled, blend in a blender although the texture won't be the same. You may just want to start over.

• If broken, try whisking in a little cream or water. The sauce may break if it becomes too hot. In this case cooling it off with cold water or an ice cube might do the trick.

• If too thick, add a little boiling water.

• If too thin, you may have added the butter too fast.

If you have the time (and an extra half pound of butter lying around), just start over! That's what I ended up doing after finding my first batch too runny. I put it back on the stove to reheat since it had been sitting out too long for the photo shoot(!), which quickly caused it to break into many pieces!

You can find the recipe for Hollandaise in the book Le Cordon Bleu at Home. To see how the rest of the group fared (all 3 of us!) with this week's recipe, click here and then click on each blogger!

Sauce Moutarde

For a variation, you can add Dijon mustard (or whatever mustard you want) to taste. This version tasted great on a ham roast we had. I also tried it on asparagus and the Eggs Benedict and loved it on these too.

Recipe: Eggs Benedict

Serves: 1

1 English Muffin, toasted
1-2 slices back bacon, cooked
1 poached egg
Hollandaise sauce
Freshly ground black pepper

Tasting Notes
Eggs Benedict always seemed so special when we went out for breakfast. Everyone else would order it, and I would order my French Toast. Now, though, I've discovered how much I love this heart-unfriendly breakfast fare and plan on making it more often. The hollandaise was rich and buttery, smooth and creamy, with a slight tang from the lemon. The hardest part of this dish is getting the poached egg properly poached (not too underdone and not too overdone). I still need practice on this front.

The mustard version was delicious too, perfect for a variation on Eggs Benedict or with ham and asparagus.

The best tip I learned was to use a thermos to store the Hollandaise sauce in until you're ready to serve. Brilliant, I tell you.

I always thought demi-glace (pronounced DEHM-ee glahs) was stock reduced by half. If only it were that simple and "basic" as the title suggests!

A simple stock reduction refers to glace de viande (pronounced glahs duh vee-AHND). Traditional demi-glace is much more involved, literally means half glaze, and requires even more hours in the kitchen babysitting stock. It is half stock and half Espagnole (pronounced ehs-pah-NYOHL) sauce that are then reduced by half. This traditional method is a little passé according to an article on StyleForum, which suggests that reductions are hot and roux is not. But some believe that the time spent on making demi-glace the traditional way using both brown stock and Espagnole sauce is well worth it.

Espagnole Sauce
So, what is Espagnole sauce? Espagnole sauce is the most basic brown stock in French cuisine, has the distinction of being one of the five mother sauces, and has a Spanish name. You can credit the Spanish cooks at Louis XIII’s wedding who added Spanish tomatoes to the brown sauce and everyone loved it. I'm sure these cooks would have given the Iron Chefs a run for their money with their Spanish tomatoes!

Espagnole sauce is made with brown roux and brown stock. Bacon, the usual aromatics (onions, celery, carrots, a Bouquet garni), and tomatoes are added. Also, Madeira or sherry is sometimes added, although the recipe I used didn’t call for it.

Process for Demi-glace
So, here’s the process to make classical demi-glace:

1. Make brown stock.
2. Make Espagnole sauce.
3. Make demi-glace.

Since I have a freezer full of stock, I just had to prepare the Espagnole sauce to get to step 3.

Thomas Keller’s Veal Stock (affiliate link) and Demi-glace

When I made veal stock, I made several versions. To make the demi-glace, I used one of the veal stocks that I roasted with tomato sauce. As I was working through this recipe, it occurred to me that Thomas Keller’s veal stock (affiliate link) involved a similar 2-step plus reduction process. His doesn't have a whiff of flour in it nor does it have bacon, but other than that I wonder if you might be able to classify it as demi-glace.

So, you can try the following three ways to get yourself to demi-glace status:

• You can reduce veal stock. This is more common these days since roux is passé and reductions save time in the kitchen. But, for the purist, this is not the path to flavor nirvana.

• You can follow the Keller way, which is to make a "veal stock #1", and then make a "veal stock #2". Then you can reduce that down to make a demi. (Keller’s stock has a more tomato-y flavor, and if you want the smoky flavor that an Espagnole sauce has, you could add the bacon in the last step.)

• You can follow the traditional method and make a stock, make an Espagnole sauce, and then make a demi.
