Lemon pickle, known as Nimbu ka Achar or Elumichai Oorugai, is a tangy, spicy, and sometimes sweet condiment made from fresh lemons, salt, and aromatic spices. It is a staple in Indian, Middle Eastern, and North African cuisines, often used to enhance rice dishes, curries, and parathas. Beyond its taste, it is prized for health benefits, being rich in Vitamin C and antioxidants, and is traditionally believed to aid digestion and boost immunity.
