Here in zone 4, very few greens sprout up until mid May at the very earliest. While friends in England start posting photos of snowdrops and daffodils in February, I have to wait until the snow clears (a few months after that…) to see the first greens unfurl. Fortunately, right after dandelions make their appearance, sorrel springs up in great, abundant heaps, just asking to be devoured.
I grow a variety of herbs and perennial greens in my potager garden, just outside my kitchen door, and it’s always a delight to bite into the first, lemony sorrel leaves when they show up after the long, cold Quebec winter. Springtime came earlier than usual this year (which was a delightful surprise), so I have chives and thyme coming up as well. Since the evenings out here are still quite chilly, I decide to gather a bunch of sorrel and put some soup together for dinner.
I grew up with sauerampfer soup, but my family’s recipe was very heavy on cream and egg yolks, and I found it to be way too heavy. I’ve adapted my own recipe to incorporate whatever’s in season (and in the fridge), and omitted the cream and eggs: I use fat-free plain yoghurt instead.
Olive oil or butter or Earth Balance (for frying)
1 small to medium onion, peeled and diced
1/2 teaspoon thyme, finely chopped
1 small bunch green onions or chives, finely chopped
2 medium potatoes, grated or finely chopped
A couple of big handfuls of sorrel leaves, shredded
4 cups of your favourite stock (I use chicken stock, but leek or onion stock works really well in this
1/3 cup plain yoghurt or sour cream (dairy or vegan)
Lemon juice (fresh, not concentrated!)
Salt and black pepper
Heat your butter or oil in a large stock pot on medium-high heat, and add the onions and thyme, stirring often until the onions soften and start to turn golden.
Add the stock, green onions, and potatoes, and stir well. Bring this mixture to a boil, then reduce to a simmer. Let that bubble away merrily until the potatoes have softened.
Toss in those sorrel leaves, which will turn a sort of murky olive green as soon as it hits the heat: don’t be alarmed, it’ll still taste fabulous.
Use an immersion blender to puree approximately half of the soup, or scoop out half of it and put it through a standard blender or food processor, adding it back to the pot when you’re done. If you find the soup too thick, feel free to add some more stock to thin it out. Stir in the yoghurt or sour cream, and a tablespoon or so of lemon juice. Add salt to taste, and feel free to add more lemon if you like as well.
The sour cream or yoghurt are optional and are just used to make the soup creamy, but you can also use pureed cannellini beans if you’d like to add protein and a silky texture. Some people prefer not to mix the sour cream into the dish, but instead add a dollop of it into the bowl just prior to serving, along with chopped raw sorrel, parsley, or dill.
I made this soup with what I had on hand, but it can be adapted so many ways. Fresh sweet green peas make a great addition as soon as they’re available, and swapping out half of the sorrel for spinach adds more iron and greenness to the pot. I’ve added leftover roasted zucchini, used cauliflower instead of potato… but the one common denominator is always the gorgeous lemony bite from the sorrel.
