Taste and Texture
Scorzonera’s subtle flavor profile is often compared to oysters, giving rise to its nickname “vegetable-oyster.”
- Flavor: Mild, delicate, slightly earthy with an oyster-like nuance. Not pungent or bitter.
- Texture: Creamy, smooth, somewhat nutty when cooked well. Similar to parsnips or young potatoes, but less starchy.
- Best Preparation for Flavor: Boiling or steaming preserves its delicate taste; frying intensifies its earthiness.
Scorzonera’s taste is celebrated in French and Belgian cuisine, where it’s treated as a delicacy. It pairs well with mild cheeses, fresh herbs, well-cooked meats, and other root vegetables.
Buying, Storing, and Preparing
- Buying: Look for firm, straight, unblemished roots with intact skin. Avoid limp or moldy sections.
- Storing: Unwashed roots keep well in cool, dark, ventilated conditions, or stored in sand to retain moisture and prevent sprouting.
- Preparing: Wash thoroughly. Peel or scrape off the black skin; cut roots just before cooking to prevent browning (optionally store peeled roots in acidulated water).
- Handling: Roots exude a sticky latex when cut; gloves or lemon juice can help reduce staining on hands.
Growing Scorzonera: Tips for Gardeners
Although a perennial by nature, scorzonera is most often grown as an annual for culinary use .
- Sowing: Direct seed in fall, winter, or early spring, ½-inch deep.
- Spacing: Plant 2–4 inches apart in rows, with rows 18–24 inches apart .
- Climate Requirements: Thrives in cool seasons; optimum monthly average temperature: 55°F–75°F (monthly max: 85°F; min: 45°F).
- Soil: Prefers loose, well-drained, rich soils free of stones.
- Harvest: Typically ready from early November; can be harvested direct or roots can be lifted and stored .
- Bolting Resistance: Modern varieties show strong resistance to premature flowering, allowing for better root yields .
- Pests/Disease: Scorzonera is generally untroubled by insect pests or disease.
Risks and Considerations
- Allergies: Scorzonera is generally safe and rarely causes allergic reactions; people sensitive to latex might wear gloves during preparation.
- Traditional Claims: Ancient medicinal uses—e.g., anti-plague and anti-venom—are not supported by scientific evidence.
- Farming Challenges: Roots are long and require deeply tilled, stone-free soils for best yield.
