Weisser Spargel mit Sauce Hollandaise

German white asparagus with sauce hollandaise, Black Forest ham, and buttered new potatoes: the canonical Spargelzeit plate of Baden-Württemberg and Bavaria, served during the six-week window between late April and June that southern Germany observes as an unofficial national season

Origin: Schwetzingen, Baden-Württemberg, Germany

From the journey of Asparagus.

Spargelzeit (asparagus season) is one of the most ritualised food events in Germany, and possibly in all of Europe. From late April until the 24th of June (Johannistag, the feast of St John the Baptist, by which date the asparagus plant needs to be left to recover), white asparagus dominates German restaurant menus, market stalls, farm shop signs and newspaper food pages. The Schwetzingen area of Baden-Württemberg has been cultivating white asparagus since the 1600s, and the town's Spargelfest is one of the oldest asparagus festivals in the world. German white asparagus is grown in deep, carefully maintained sandy-loam ridges, cut by hand just below the surface before the tips emerge, and graded by diameter: extra-thick extra-class asparagus is the most prized, with a diameter above 26mm. The white asparagus of the Rhineland, Bavaria, and Lower Saxony has PDO protection under EU law. The canonical plate is always the same: thick white spears, sauce hollandaise (made in the French style, not a packet), sliced Schwarzwälder Schinken (Black Forest ham) or cooked ham, and small boiled new potatoes glistening with butter and parsley. Nothing else. Germany consumes more than 57,000 tonnes of white asparagus per year, almost all of it during the six-week Spargelzeit.

Ingredients

Vegetable

  • 1 kg white asparagus

Cooking water

  • 1 tsp salt
  • 1 tsp sugar
  • 20 g butter (for cooking water)

Hollandaise

  • 3 egg yolks
  • 180 g unsalted butter, clarified
  • 1 tbsp dry white wine
  • 1 tbsp cold water
  • 1 tbsp fresh lemon juice
  • 0.5 tsp fine white pepper

Accompaniment

  • 200 g Schwarzwälder Schinken (Black Forest ham) or high-quality cooked ham, sliced
  • 600 g small new potatoes
  • 30 g butter (for potatoes)

Garnish

  • 2 tbsp fresh flat-leaf parsley, chopped

Method

  1. Peel the white asparagus generously from just below the tip to the base, removing the tough outer skin. Trim the woody ends to create spears of uniform length.
  2. Clarify the butter for hollandaise: melt the unsalted butter gently over low heat, skim the white foam from the surface, then carefully pour off the clear golden liquid, leaving the white milk solids behind. You need 180g of clear, warm clarified butter.
  3. Cook the potatoes in salted water until tender, drain, and toss with butter and parsley. Keep warm.
  4. Cook the asparagus: stand the peeled spears upright in a tall pot with salted water reaching three-quarters up the stalks (tips above water). Add the sugar and butter to the water. Cover loosely with foil and bring to a boil. Reduce heat and simmer for 15–20 minutes until the stalks are tender when pierced.
  5. Make the hollandaise while the asparagus cooks: place the egg yolks, white wine, and cold water in a heatproof bowl. Set over a pan of barely simmering water (bain-marie): the bowl must not touch the water. Whisk continuously until the yolks thicken to a pale, ribbon-like consistency that holds its shape when the whisk is lifted: about 3–4 minutes.
  6. Remove the bowl from the heat. Begin adding the warm clarified butter drop by drop while whisking constantly: this builds the emulsion. Once the sauce visibly thickens after the first few additions, you can add the butter in a thin, steady stream, whisking constantly.
  7. Season the hollandaise with lemon juice, white pepper, and salt. Taste: it should be rich, buttery, clearly lemony, and with a gentle warmth from the pepper. Keep warm in the bain-marie (off the heat) until ready to serve.
  8. To serve: arrange the hot asparagus on warm plates. Place slices of ham alongside. Add the buttered potatoes. Spoon hollandaise generously over the asparagus. Serve immediately.

Notes

Sauce hollandaise does not hold well and should be made immediately before serving. If you must make it in advance, keep it in a warm (not hot) bain-marie for up to 30 minutes, whisking occasionally to prevent a skin forming. The German tradition uses salted, not smoked, ham for Spargelzeit: Schwarzwälder Schinken is technically a dry-cured, cold-smoked product, but the version sold thinly sliced for Spargelessen is usually mild. Any good quality cooked or cured ham works.

Asparagus

Asparagus officinalis

VegetablesAsparagaceae

🌍Origin

Nile Delta and Eastern Mediterranean — c. 3000 BCE

🌱Domestication

Wild Asparagus officinalis grows naturally across a vast range from the steppes of Central Asia to the Atlantic coasts of Europe and the marshlands of the Nile Delta: one of the most geographically widespread of all cultivated vegetables even before human agency. The earliest evidence of asparagus being valued as food comes from ancient Egypt: carved reliefs at Saqqara dating to approximately 3000 BCE depict bundled asparagus spears among temple offerings, indicating it was already sufficiently prized to be presented to the gods. Greek naturalist Theophrastus (c. 371–287 BCE) described its cultivation in Historia Plantarum, and the name itself (asparagos in Greek) is where the word in every European language derives. Three culinarily significant forms have emerged from a single species: green asparagus, the standard cultivated form grown in open sunlight; white asparagus (Weissspargel, asperge blanche), the same plant grown in earthed-up darkness, cut before any exposure to light can trigger chlorophyll development, producing a paler, milder, more tender and slightly more bitter vegetable of completely different culinary character; and purple asparagus, of which the Violetto d'Albenga variety of Liguria is the most celebrated, carrying higher anthocyanin content and a slightly sweeter flavour before it turns green when cooked. The wild form (Asparagus acutifolius, the thin-speared, intensely bitter wild asparagus of the Mediterranean maquis and hillsides) remains a foraged delicacy across southern Europe and North Africa, its flavour incomparably more concentrated than any cultivated variety. A fourth distinct species, Asparagus racemosus (shatavari), is the sacred Ayurvedic medicinal asparagus of the Indian subcontinent, with an entirely separate history in Indian traditional medicine.

Global Voyage

The Romans were asparagus's most passionate early champions, transforming it from a Mediterranean wild-harvest tradition into an intensively cultivated luxury crop. Emperor Augustus Caesar made it a byword for speed ('velocius quam asparagi coquuntur', faster than cooking asparagus), which reveals both how quickly the Romans cooked it (briefly, barely) and how familiar it was to every Roman. Pliny the Elder praised the asparagus of Ravenna in his Natural History as the finest in the empire; the cook Apicius recorded multiple preparations in De Re Coquinaria. Roman legions introduced cultivation across the empire from Syria to Britain, and the word remained essentially unchanged from Greek into Latin and from Latin into every modern European language. Medieval Europe inherited asparagus cultivation but largely forgot the Roman enthusiasm; the vegetable retreated to monastery gardens and apothecary plots, sustained by Arab physicians like Ibn Sina (Avicenna), whose Canon of Medicine (c. 1025 CE) catalogued its medicinal properties in detail: diuretic, tonifying to the kidneys, useful in treating dysuria and liver ailments. The Renaissance revival in Italy brought asparagus back to the table with full force. Bartolomeo Scappi, cook to Pope Pius V, included asparagus prominently in his monumental Opera dell'arte del cucinare (1570), and the green asparagus of the Veneto became the foundation of risotto agli asparagi. The white asparagus story diverges from Italy: the first documented cultivation of blanched white asparagus appears at Bassano del Grappa, where the Asparago Bianco di Bassano (now DOP-protected) was documented from the 16th century. From Italy the technique moved north: the Elector Palatine's court at Schwetzingen established white asparagus cultivation in the mid-17th century, and the Spargelzeit tradition became embedded in southern German culture to a degree unmatched by any other vegetable in any European nation. Germany now consumes more than 57,000 tonnes of white asparagus annually during Spargelzeit. The asparagus of Argenteuil north of Paris became France's most celebrated variety in the 18th century, feeding the Parisian fine dining tradition. English settlers carried asparagus to New England, where the Connecticut River valley at Hadley, Massachusetts proved ideal; Hadley was America's asparagus capital through much of the 19th century. The late 20th century produced a final chapter: Peru's Ica Valley, irrigated by Andean meltwater, proved capable of producing asparagus year-round, and American agronomic investment transformed Peru into the world's largest asparagus exporter by value. Japan's Hokkaido adopted the vegetable with characteristic intensity, producing the beloved aspara bacon of the izakaya tradition.

🍽Modern Culinary Role

China is the world's largest asparagus producer by volume (producing more than 90% of global supply by some measures), though the bulk is for domestic consumption and the canned export market rather than the fresh premium trade. Peru is the leading exporter of fresh asparagus globally, followed by Mexico, Spain, and Germany. White asparagus holds court in Germany, France, Belgium, and the Netherlands, where it commands prices three to five times that of green asparagus. Germany's Schrobenhausener Spargel and Beelitzer Spargel of Brandenburg both hold PDO status. Italy's Asparago Bianco di Bassano del Grappa and the green Asparago di Badoere are both DOP-protected. The Asparagus of the Vale of Evesham in England is PGI-protected. Japan's premium asparagus from Hokkaido is sold in high-end gift sets during the asparagus season, individually inspected and wrapped. Purple asparagus remains a specialty product: the Violetto d'Albenga of Liguria is grown in very limited quantities and prized for its nutty sweetness and anthocyanin richness.
