Asparagus With Boznersauce, A ‘Sauce from Bolzano’

‘salsa bolzanina’

Boznersauce is a springtime specialty from Bolzano in Alto-Adige, the Italian province that together with Trentino forms one of Italy’s five autonomous regions, Trentino-Alto-Adige. Annexed from Austria by the Kingdom of Italy at the end of World War I, Alto-Adige—Südtirol in German or South Tyrol to English speakers—has retained its culturally Austrian identity in the decades since, despite an aggressive Fascist-era ‘Italianization’ program and a significant influx of Italians in the post-WWII period. Officially part of Italy for nearly a century, today Alto-Adige is still comprised predominantly of native German speakers, though Italian and German are both official languages.

The intersection of Italian and Germanic influences in South Tyrol characterizes many aspects of local culture, including cuisine. Further shaped by Viennese and Hungarian traditions, Alto-Adige’s culinary scene has earned a reputation in recent years as a gastronomic mecca, with 23 Michelin stars as of 2016. Interestingly, many non-Italian dishes, items like speck, würstel, strudel, and knödel, have entered the Italian national food canon via Alto-Adige.

The people of the Bolzano area enjoy this hollandaise-like sauce, whose name means ‘of Bozen’ (German for Bolzano), alongside fresh asparagus during Easter Sunday lunch.

Ingredients for 4

2 bunches green or white asparagus
1 cup dry white wine
2 cups water

For the sauce:
4 eggs, hard-boiled
100 ml ‘light’ olive oil or seed oil of choice
1 Tbsp white wine vinegar
1 Tbsp mustard
1 Tbsp fresh parsley, minced
1-2 Tbsp fresh chives, chopped
3 Tbsp beef broth
¼ tsp white pepper
½ tsp salt

Instructions

To make the Boznersauce, start by boiling the eggs for 8 minutes and remove from the water immediately. Heat the broth and keep warm.

When cool enough to handle, peel the eggs. Slice them in half and remove the yolks, placing the yolks in a bowl and setting the whites aside. Add the vinegar, mustard, broth, salt and pepper to the yolks. Whisk until creamy (a few lumps are fine). Slowly drizzle in the oil while whisking continuously until you have a thick, smooth cream. Add the minced parsley and combine. Chop the egg white to a medium-fine mixture. Add to the egg cream and combine. Set aside at room temp while you make the asparagus.

Bring the water and wine to a simmer. Snap the tough ends off the asparagus and cook in the simmering water for 5 minutes and remove promptly. Arrange the asparagus on serving dishes and place generous scoops of the Boznersauce over them. Dust with the chopped chive.
