Wash the baby potatoes and put them in the simmering basket.
Cut off the woody ends of the asparagus. Place the butterfly whisk in the Varoma® and place the asparagus spears on top. (Inserting the butterfly whisk into the Varoma® leaves more steam slots free, which improves steam circulation). Sprinkle the asparagus with ½ teaspoon of salt.
Then add water and 1 teaspoon of salt to the mixing bowl, attach the simmering basket, place the Varoma® on top and cook 25 min. / Varoma® / level 1.
Set the Varoma® down, remove the cooking baskets and keep both warm.
Pour off the water and continue with the preparation of the hollandaise sauce.
Place the butter in the mixing bowl and melt 4 min. / 70° C / level 2. Then remove the butter from the mixing bowl.
Now insert the butterfly whisk. Add the water (or wine), lemon juice, egg yolk, salt and pepper to the mixing bowl and heat 2 min. / 70° C / level 4.
Then whip 4 min. / 70 °C / level 4. Slowly pour the melted butter onto the mixing bowl lid so that it flows in a thin stream past the measuring cup and onto the running blade in the mixing bowl.
Finally, remove the butterfly whisk and serve the sauce immediately with the asparagus and baby potatoes.
Notes
If you like the asparagus even more firm to the bite, you can shorten the cooking time.
If the sauce becomes too thick, you can dilute it with a little water or white wine.
The hollandaise sauce should be served immediately, otherwise it may curdle.
