California is a state known forΒ its water problems and a recent drought. If you liveΒ in Southern Cali, you are used to the naturally dry, yellowish landscape for most of the year. This year, the landscape has changed dramatically due to abundant rainfall.Β All of a sudden,Β everything turned green! The rain, however, brought a lotΒ of weeds to the surface, but that’s something I love because I oftenΒ walk my dog through the neighborhood and purposely look around for rare edible weeds and plants. My area just happens to be bursting with one pretty-looking weed,Β somewhat like a clover or shamrock, with bright yellow flowers. The plant has an exceptionally high content of oxalic acid, which causes an acidic taste. Hence, its scientific name is OxalisΒ or, if you prefer, the common terms: sour-grass, or wild sorrel.

Ever since IΒ left Poland, I have been craving thatΒ pleasant tartΒ flavor. However, the sorrel I remember fromΒ Poland wasn’t the same as the weedΒ from my neighborhood. It looked more like a spinach plant. Its name was the common sorrelΒ orΒ garden sorrelΒ (Rumex Acetosa). I have often wondered why that plant was so hard to get inΒ the U.S. Frankly, I was able to spot it only once, at the local farmers’ market.Β Poles cookΒ leafy sorrel mostly one way only. They make soup out of it. It can be purchased as a concentrate in a jar during the winter months.
When I saw that wild sorrel growing all over my neighborhood, I started wondering if I were to use it to make soup, would it tasteΒ the same as the Polish one made of leafy sorrel? I decided to give it a try, and the results were pretty successful. My California Sorrel Soup had almost an identical flavor and texture to my beloved Polish Sorrel Soup. So,Β now I know I can cook sorrel soup any time of the year βοΈ πΌπ πΌ π πΌ βοΈ
A coupleΒ more things of interest.Β The soup has a strange, unattractive, swamp-like color and texture. A friend named it a “swamp soup”. Its flavor is acquired, but if you like tart food and are an adventurous foodie, you might really like it. The soup is always eaten with hard-boiled eggs, which are believed to neutralize some side effects of sorrel’s acidity.
And that’s it! I think you should try to make this soup before the sorrel season ends!

Ingredients (for 4 people):
- 1/3-1/2 lbs sour grass/wild sorrel (set aside a few smaller springs with leaves and flowers for garnish)
- 1/2 lb baby potatoes (preferably Golden Yukon)
- 4 medium carrots (peeled)
- 1/2 medium celeriac (peeled and cubed)
- 3 cloves of garlic (peeled and finely chopped)
- 2-3 tsp whole cumin (freshly toasted and finely ground)
- 1 1/2-2 quarts chicken or beef broth (or vegetable)
- 1/4 cup heavy cream
- Salt and ground black pepper (to taste)
- hard-boiled eggs (2 per person)
- Boil bullion with celeriac, carrots, and potatoes with skin on (until carrots are al dente and potatoes cooked through). Take all vegetables (except for celeriac) out of the broth and set aside. Add crushed cumin and sorrel and keep boiling until the sorrel gets wilted and starts falling apart (it will change color from bright green to “muddy” dark green). Using a hand blender, puree the contents of the pot until smooth. Add heavy cream, salt, and pepper to your taste. Boil for the next 20-30 minutes, then add the vegetables.
- Pour the soup with vegetables into the soup bowl, add hard-boiled eggs, and cut them in half. Garnish with sorrel springs and flowers. If you prefer, serve with your favorite bread.
Enjoy and Happy Spring!

Pingback: This dark, green soup made out of California wild sorrel might surprise you | FlyB Kulinaria
THANK YOU so much for posting the photo of this plant and description of what it tastes like! I lived in California as a child and we used to pick this raw and chew on the stems when we were in the mood for something sour. I have been trying to describe this to my husband and didn’t know the correct name. Now I can show him that it is a real thing! It’s too bad that it doesn’t grow in this form in Pennsylvania; I miss it.
Hi Becky! I am glad my write up help to solve the mystery! Thanks for reading!

We have this in our garden here in the Philippines! I am building an edible garden with local* weeds and plants. Up until now, the wild sorrel has not come up in my searches as edible! I have only kept it as pretty groundcover and for our stingless bees. Thank you for this! Will definitely try the soup for ourselves!
*Preferably endemic, but introduced ok, too.
Thank you for checking my post. If you like acidic foods I really recommend this soup. It’s really one of my favorites π It’s a great edible weed π
