Sourgrass Potato Soup

Sourgrass, or Oxalis, is a widely recognized wild plant known for its distinctive tangy, lemon-like flavor, courtesy of the oxalic acid in its leaves. This unique taste makes sourgrass an excellent addition to various dishes. Besides its delightful flavor, sourgrass is rich in vitamin C and antioxidants, making it a nutritious and vibrant ingredient in your culinary repertoire.

Identifying Sourgrass

Here’s how you can identify sourgrass in the wild:

  • Leaves: Sourgrass features trifoliate leaves, each stem supporting three heart-shaped leaflets, resembling clover.

  • Flowers: The plant produces small, yellow flowers with five petals that typically bloom in clusters.

  • Stems: Its stems are often reddish and juicy, adding to the plant's unique look.

  • Taste: The definitive way to identify sourgrass is by tasting a small leaf, which should have a bright, tangy, lemon-like flavor.
