Growing up in the lush landscapes of British Columbia, spring held a special kind of magic. Among the many simple pleasures, foraging for wild sorrel growing abundantly in the ditches along our country roads stands out vividly. Those mouth-puckeringly sour leaves were more than just a snack; they were a delightful challenge, akin to chewing rhubarb stalks straight from the garden. It was a test of toughness among us children. “Nah, it’s not sour at all! Watch me eat this whole leaf!” we’d boast, determined not to show any weakness, lest we be caught puckering up or, heaven forbid, eating fewer leaves than our friends.

This playful tradition continued with my own children. They’d often bring me a piece of sorrel, mischievously claiming it was spinach or a sweet stevia leaf. Then, with feigned nonchalance, they’d wait for my reaction. I’d play along, taking a dramatic bite, then making exaggerated puckering faces and horrible groans as I chewed the distinctly sour, lemony leaves. Their joyful giggles and triumphant shouts of having “fooled Mommy again” were the sweetest reward. To this day, the mere thought of sorrel brings a genuine smile to my face.

Beyond these cherished memories, sorrel also makes me smile because it evokes the wonderful, creamy-tangy flavor of my Oma Bose’s sorrel soup. While I can no longer ask her for her exact recipe, I believe I’ve come incredibly close to recreating that comforting taste. She might have occasionally added a touch of bacon, and I sometimes do too. A dollop of sour cream stirred in at the end was also a possibility, though sorrel itself provides such a lovely, natural tang that it often isn’t strictly necessary. This simple, creamy version feels perfectly authentic to her spirit and my recollection.

Understanding Sorrel: The Zesty Herb of Spring

The German word for sorrel is Sauerampfer, which translates directly to “sour dock.” In our family, however, we affectionately called it Sauer-rampel. Whether this was a charming dialectal variation or simply our own unique twist on the word, it highlighted the herb’s defining characteristic: its delightful sourness. Sorrel (botanical name: Rumex acetosa) is an incredibly easy herb to grow, making it a fantastic addition to any home garden. Much like lovage, it’s a remarkably self-sufficient perennial, reliably providing some of the very first vibrant green shoots to emerge from the ground each spring. These early leaves are a true harbinger of the warmer months to come. A handful of freshly sliced sorrel leaves can instantly elevate a simple salad, adding an invigorating burst of lemony brightness that awakens the palate.

Sorrel is not just a flavor enhancer; it also offers a surprising array of nutritional benefits. Rich in Vitamin C, it’s a natural antioxidant powerhouse. It also contains vitamins A and B, potassium, and magnesium. Historically, sorrel has been used for its medicinal properties, particularly as a diuretic and a digestive aid. Its slightly tart, almost citrusy flavor makes it a versatile ingredient, perfect for cutting through richer dishes or adding a fresh dimension to lighter fare.

Growing Sorrel in Your Garden

For as long as I’ve had a garden, I’ve dedicated a peaceful, undisturbed corner to a patch of sorrel. While there are different varieties, French Sorrel (Rumex scutatus) is widely regarded as the best choice for its tender leaves and superior flavor profile. It tends to be less fibrous and possesses a more refined lemony tang than common sorrel (Rumex acetosa). If you’re eager to get started, purchasing a young plant or obtaining a piece from a friend’s established patch will yield results much faster than growing from seed. Sorrel is a wonderfully well-behaved plant; it returns faithfully year after year without becoming invasive or wildly out of control.

To ensure a continuous supply of those tart, flavorful leaves throughout the summer, it’s important to pinch out any flowering stalks as they appear. This practice encourages the plant to put its energy into producing more foliage rather than seeds, rewarding you with an abundance of fresh sorrel perfect for jazzing up summer salads or, of course, making my Oma’s delightful sorrel soup. Its resilience and ease of care make it a true garden gem, and it truly gifts me with a reason to smile every single time I walk by its vibrant green leaves.

Tips for Harvesting and Using Sorrel

Harvesting sorrel is simple: just pick the outer leaves as needed, leaving the inner ones to grow. For the best flavor and texture, harvest young, tender leaves before they become too large or tough. If your plant is producing a lot, you can blanch and freeze excess sorrel to enjoy its unique flavor long after the growing season has ended. Beyond soup and salads, sorrel shines in many other culinary applications. It pairs beautifully with fish and poultry, can be incorporated into sauces (like a classic French sorrel cream sauce), blended into pestos, or even used in omelets and quiches for a sophisticated tang.

Kitchen Frau Notes: The quality of your stock can truly elevate this soup. While homemade chicken stock offers the richest, most nuanced flavor, a high-quality purchased stock will also yield excellent results. For a vegetarian version, simply substitute vegetable stock.

Creamy Sorrel Soup Recipe

Ingredients:

2 tablespoons unsalted butter
2 medium onions, diced (about 2 cups / 500ml)
1 cup (240ml) diced celery
½ teaspoon salt, plus additional to taste
¼ teaspoon ground white pepper
1 lb (450gms) starchy potatoes, peeled and diced into ½-inch (1cm) cubes (approximately 2 generous cups)
4 cups (960ml) good quality chicken stock (or vegetable stock for a vegetarian option)
1 bay leaf
2 tablespoons sweet rice flour (or all-purpose flour for a thicker soup; for gluten-free, use a gluten-free all-purpose blend or cornstarch slurry)
½ cup (120ml) light cream (or half-and-half; for dairy-free, use full-fat coconut milk or a plant-based cream alternative)
4 cups (4 oz / 115gms) fresh sorrel leaves, coarsely chopped
Optional garnishes: a dollop of sour cream, fresh chives, a sprinkle of smoked paprika, or a few crumbles of crispy bacon

Instructions:

Prepare the Base: In a large, heavy-bottomed saucepan or Dutch oven, melt the butter over medium heat. Add the diced onions, celery, initial ½ teaspoon of salt, and ¼ teaspoon of white pepper. Sauté gently, stirring occasionally, until the vegetables are softened and translucent, which should take about 5 to 10 minutes. This slow sautéing process builds a rich flavor foundation for your soup.
Add Potatoes and Stock: While the aromatic vegetables are sautéing, prepare your potatoes by peeling and dicing them into uniform ½-inch (1cm) cubes. Add the diced potatoes, chicken (or vegetable) stock, and the bay leaf to the saucepan. Increase the heat to bring the mixture to a gentle boil. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 15 minutes, or until the potatoes are fork-tender.
Create the Thickening Slurry: In a small bowl, whisk together the sweet rice flour (or all-purpose flour) and the light cream until the mixture is completely smooth and free of any lumps. If using regular flour, you can also vigorously shake it in a small jar with the cream for a lump-free result. This slurry will give the soup its desirable creamy texture.
Thicken the Soup: Slowly whisk the flour and cream slurry into the simmering soup. Continue to stir gently as you bring the soup back up to just a boil. The soup will begin to visibly thicken as it heats.
Incorporate the Sorrel: While the soup is thickening, trim any tough stems from your fresh sorrel leaves and discard them. Coarsely chop the clean leaves. Once the soup begins to bubble after adding the slurry, immediately stir in the chopped sorrel. Heat the soup just until the first few bubbles appear again. It’s fascinating to watch the sorrel leaves transform almost instantly from a bright, vibrant green to a deeper, olive green hue upon contact with the hot soup – a sure sign their tangy flavor is melding beautifully.
Final Seasoning and Serve: Taste the soup and adjust the seasoning as needed, adding more salt and pepper to your preference. Serve this comforting Creamy Sorrel Soup hot, garnished with a dollop of sour cream for extra richness, a sprinkle of fresh chives, or a few crumbles of crispy bacon for a savory touch. Fresh crusty bread makes an excellent accompaniment.
