How to Eat Black Salsify?
The subtle, sophisticated flavor of black salsify makes it wonderfully versatile in the kitchen, often taking center stage in European cuisine. Its unique taste becomes more apparent when prepared simply.
- Steamed or Boiled: Simply steam or boil the peeled roots until tender, then dress with butter, salt, and a squeeze of lemon juice to highlight its “oyster” flavor.
- Roasted: Roasting brings out a nutty sweetness. Toss peeled and chopped salsify with olive oil, salt, pepper, and herbs like thyme or rosemary.
- Creamy Purees: Cooked salsify can be pureed into a silky, flavorful soup or a creamy side dish, often replacing mashed potatoes for a lighter alternative.
- Fried: Cut into chips or fritters, the cooked roots can be lightly battered and fried until golden and crispy.
- Gratins and Bakes: Layer sliced, blanched salsify in a creamy sauce with cheese for a comforting gratin.
- Added to Soups and Stews: Its firm texture holds up well in longer-cooking dishes, absorbing flavors beautifully.
- Young Greens: The young leaves of black salsify can also be harvested and added to salads, offering a mild, slightly bitter note.
Growing Black Salsify
Growing black salsify requires a bit of patience, but the unique reward is well worth the wait! While it’s a biennial plant (meaning it flowers and sets seed in its second year), it’s almost always grown as an annual for its edible root. It’s a cool-season crop that needs a long growing season, typically 120 days or more.
The most crucial factor for straight, well-formed salsify roots is deep, loose, stone-free soil. Think of it like growing a long, slender carrot! If your soil is heavy clay or very rocky, consider growing it in raised beds filled with a suitable mix, or thoroughly amend your native soil with plenty of well-rotted compost. A pH between 6.0 and 6.8 is ideal. Soil that has been recently manured can cause the roots to fork, so it’s best to plant in an area where organic matter was added for a previous crop.
Black salsify seeds have a relatively short viability, so always use fresh seeds for the best germination rates. Direct sowing is essential, as salsify does not transplant well, and disturbing the taproot can lead to forking. Sow seeds in early spring, as soon as the soil can be worked and has warmed to at least 50°F (10°C). Planting too late in the season might mean the roots don’t fully develop before winter.
Sow seeds about 1/2 inch deep and 1 inch apart in rows spaced 12-18 inches apart. Germination can be slow and erratic, taking 2-3 weeks, so don’t despair if they don’t pop up immediately. Once the seedlings emerge and have their first true leaves, thin them carefully to 3-4 inches apart. Adequate spacing is vital for the development of nice, thick roots.
Consistent moisture is incredibly important for black salsify, especially during germination and early growth. Uneven watering can lead to tough, woody roots or splitting. Aim for about 1 inch of water per week, making sure the moisture penetrates deeply into the soil. Mulching around the plants with straw or aged compost will help retain soil moisture, suppress weeds, and keep the soil temperature consistent.
As a relatively slow grower, black salsify needs a weed-free environment to thrive. Weeding by hand is often best near the plants to avoid damaging the delicate roots. Since they are generally light feeders, particularly in rich, compost-amended soil, additional fertilizer isn’t usually necessary. Avoid high-nitrogen fertilizers, as they will promote leafy growth at the expense of root development.
Black salsify is generally quite resistant to most pests and diseases. However, keep an eye out for common root-related issues like wireworms, which can affect carrots as well. Crop rotation is always a good practice to prevent the buildup of soil-borne problems.
The best part is the harvest! Black salsify typically takes 120-150 days to mature, so it’s a patient gardener’s reward. The roots are usually ready to harvest from mid-autumn onwards, and many gardeners find their flavor improves after the first few frosts, becoming sweeter and more tender. To harvest, use a garden fork to carefully loosen the soil around the roots before gently lifting them. They are quite brittle and can snap easily, so avoid pulling directly. You can leave the roots in the ground throughout winter in mild climates, harvesting as needed. In colder areas, cover the bed with a thick layer of straw or mulch to protect them from deep freezes. For longer storage, lift the roots before severe freezing and store them unwashed in slightly damp sand or sawdust in a cool, dark, frost-free location like a root cellar.
Tips and Tricks
- Prepare Your Soil: This is the most crucial step! Deep, loose, stone-free soil is paramount for long, straight roots.
- Fresh Seeds are Key: Black salsify seeds lose viability quickly, so always buy fresh seeds each year for the best germination.
- Don’t Transplant: Sow seeds directly where you want them to grow to avoid disturbing their sensitive taproots.
- Patience is a Virtue: Black salsify is a slow grower. Give it the time it needs, and the delicious reward will be worth it!
- Frost Sweetens: Don’t be afraid of light frosts; they can actually improve the flavor and tenderness of the roots.
- Handle with Care: The roots are brittle and can break easily, especially during harvest. Dig carefully!
- Watch for Milky Sap: When you peel or cut black salsify, it releases a sticky, milky white sap. Work quickly or peel under running water to prevent staining your hands (though it washes off easily).
Black Salsify Cuisine
Black salsify, with its unique “oyster plant” flavor, is a versatile and elegant vegetable that can elevate many dishes. Its delicate taste pairs well with both rich and light ingredients.
Here’s a simple and classic recipe to showcase the gourmet appeal of your homegrown black salsify:
Roasted Black Salsify with Herbs and Lemon
This preparation allows the delicate flavor of the black salsify to truly shine, with a hint of citrus and fragrant herbs.
Ingredients:
- 1 pound black salsify (about 4-6 roots), scrubbed clean
- 2 tablespoons olive oil
- 1 tablespoon fresh lemon juice
- 1-2 sprigs fresh thyme or rosemary, leaves picked and chopped (about 1 teaspoon)
- Salt and freshly ground black pepper to taste
- Optional: a sprinkle of fresh parsley or chives for garnish
Instructions:
- Prepare the Salsify: This is the trickiest part! Have a bowl of water with a squeeze of lemon juice ready. Working quickly, peel the black salsify roots with a vegetable peeler or small paring knife. As you peel, immediately place the peeled roots into the lemon water to prevent discoloration (they oxidize quickly like apples or artichokes). Once peeled, cut the salsify into 2-3 inch pieces, or leave them whole if they are slender.
- Blanch (Optional, but Recommended): For very tender salsify and to further prevent discoloration, you can quickly blanch the peeled pieces. Bring a pot of lightly salted water to a boil. Add the salsify pieces and cook for 3-5 minutes, until slightly tender-crisp. Drain well. This step also helps reduce any stickiness from the sap.
- Season and Roast: Preheat your oven to 400°F (200°C). In a bowl, toss the blanched (or unblanched, if skipping blanching) salsify pieces with olive oil, fresh lemon juice, chopped thyme or rosemary, salt, and black pepper until evenly coated.
- Roast: Spread the seasoned salsify in a single layer on a baking sheet. Roast for 20-30 minutes, or until the salsify is tender and slightly caramelized at the edges. Turn them once or twice during roasting for even cooking.
- Serve: Transfer the roasted black salsify to a serving dish. Garnish with fresh parsley or chives if desired. Serve immediately as an elegant side dish to roasted chicken, fish, or simply as a delightful vegetable course.
