Sourgrass Lentil Soup

Sourgrass, or Oxalis, is a fascinating wild plant that's widely available in many regions. Known for its tangy, lemon-like flavor due to the oxalic acid in its leaves, sourgrass is a versatile ingredient that brings a unique zest to dishes. Beyond its delightful taste, sourgrass is packed with vitamin C and antioxidants, making it a healthy addition to any meal.

Identifying Sourgrass

Recognizing sourgrass is straightforward if you know its key characteristics:

  • Leaves: The plant features trifoliate leaves, with each stem bearing three heart-shaped leaflets, much like clover.

  • Flowers: Sourgrass blooms small, yellow flowers with five petals, typically grouped in clusters.

  • Stems: Its stems are often reddish and succulent, adding to its distinctive look.

  • Taste: To confirm you’ve found sourgrass, taste a small leaf. It should have a bright, tangy flavor reminiscent of lemon.
