Tuna Steak with Green Asparagus and Hollandaise Sauce
·Prepare the fish and asparagus
Season each tuna steak simply with salt and pepper. Sear it in a hot pan for one minute on each side. Trim the dried-out, tough ends off the asparagus and lightly fry it in a knob of butter. Again, just season with salt and white pepper.
Whisk the egg yolks
Place 3 egg yolks and 2 tablespoons of white wine in a bowl set over a water bath. Whisk with a whisk, making sure the water in the pot never boils — otherwise the yolks will scramble. Add a heaped teaspoon of mustard. Season with a pinch of salt and white pepper.
Add the butter
Once the mixture has thickened, slowly drizzle in the melted, slightly cooled butter in a thin stream, whisking constantly.
Serving
Whisk up a beautiful sauce. Pour it over the asparagus. The ideal side dish? Boiled potatoes. Serve with a chilled glass of white wine, such as a Vinselekt Michlovský Grüner Veltliner.
