The combination of white asparagus, smoked salmon, and Hollandaise sauce is a classic one. With homemade Hollandaise, sous vide asparagus, and home-smoked salmon it is a lovely appetizer. You could substitute good quality store-bought smoked salmon and steam the asparagus instead, but making Hollandaise yourself is definitely worth it and not at all difficult if made using the technique I describe in this post.
Ingredients
Serves 4 as an appetizer
8 white asparagus
225 grams (.5 lb) smoked salmon
1/2 Tbsp lemon juice
1/2 Tbsp white vinegar
1 egg yolk
75 grams (5 Tbsp) butter
salt and freshly ground white pepper
Instructions
Peel the asparagus and remove the bottom 1 cm (1/2 inch). Do not peel the tips.
If you are boiling the asparagus instead of cooking them sous-vide, make a stock from the peels and bottoms first by simmering in water for an hour with a bit of salt and some white peppercorns. Bring that stock to a boil (with the peels and bottoms still in there) and add the asparagus. Turn off the heat and allow the asparagus to steep in the hot water for 20 minutes or until they are done to your liking. This way, the result will be very similar to asparagus cooked sous-vide.
To cook them sous-vide, season the asparagus with salt and freshly ground white pepper, and vacuum seal them. If using a FoodSaver-type vacuum sealer, it helps to dry the asparagus well before vacuum sealing and to arrange them sideways (i.e. not with the bottom towards the opening of the bag). Cook them sous-vide for 45 minutes at 85C/185F. Depending on the thickness of the asparagus or your personal preference, more or less time may be needed.
Slice the smoked salmon thinly with a sharp knife.
To make the Hollandaise, put an egg yolk, 1/2 tablespoon lemon juice, 1/2 tablespoon white wine vinegar, salt, freshly ground white pepper, and 75 grams of butter in cubes in a cold saucepan.
Stir over medium-low heat…
…until the butter has melted, then lower the heat…
…and keep stirring over over low heat until the sauce has thickened to the consistency of mayo.
Here I have added the liquid from the sous-vide bag to the sauce and whisked it in, to add asparagus flavor to the sauce.
Serve the asparagus with the salmon and the Hollandaise.
Wine pairing
This is great with a brut but creamy champagne, crémant, or cava. The creaminess of a sparkling wine made using a second fermentation in the bottle increases with the time the wine has been allowed to age with the lees still in the bottle, so a vintage champagne or cava gran reserva is the best choice here.
Flashback
These oysters with a Chinese black bean sauce are a famous dish from Chinese restaurant Nam Kee in Amsterdam. Not just because a book and movie have been named after them, but also because they are so good.
intrigued by yr Hollandaise version…where does it come from? it sounds a good idea

It is so much easier than the traditional technique using clarified butter. I got it from Harold McGee.

As much as I love homemade stuff, I wonder: Is homemade cold smoked salmon better than store-bought? It’s a no-brainer with hot smoked salmon. You simply can’t buy salmon mi-cuit hot smoked. But you can do this at home. Why exactly do you find homemade cold smoked salmon better. I’ve never tried it. So, it’s probaby a stupid question.

It is not a stupid question. There are two main reasons why homemade cold smoked salmon can be better than store-bought:
1) Store-bought is usually wet cured instead of dry cured, so there is more water (and less flavor) in it.
2) Store-bought is usually made with ‘smoke aroma’ instead of actually smoked with real smoke.
Of course you could buy artisan cold smoked salmon that is actually dry cured and smoked with real smoke, but most of the store-bought smoked salmon is from the supermarket and just not as good. When I have guests and serve my homemade cold smoked salmon, they always rave about it.

Stefan, thank you very much. I will try this as soon as possible. Sommer is coming. Not a good time for cold smoking. By the way, for years, I’ve used your recipes for pancetta and guanciale with great results.

That is great to hear about the pancetta and guanciale! I make a batch every winter, freeze in portions and use it all year.
You are right it is not a great time of the year for cold smoking.

Love asparagus but can usually only buy the green variety here. Am more used to serving it with Westphalian ham or similar but am drawn by the salmon. Also make my hollandaise somewhat differently and have to try your version . . . yes, do steam my asparagus 🙂 1

Hi Stefan, during the short period of availability of asparagus, we try to eat as often as possible. I some thoughts about freezing them. I tried it it once many years ago, before discovering vacuuming + sous vide, to freeze raw ones. What came out the freezer, after defrosting, was mashed asparagus, so only usable for soup.
As you always experiment a lot, did you ever try to freeze a vacuumed and cooked pack?
Best regards, Frans

I’ve never tried that, because I expect freezing will turn the asparagus mushy.
