South Indian Lemon Rasam (A broth like soup with lentils and spices) is another great way to consume lemons during winters. You can also try our Lemon Rice for Main Course.
Ingredients
Please note that all the ingredients (complete list) with measurements is mentioned in the recipe card below.

Vegetables - I add seasonal vegetables to the soup. This is the perfect "Clean your refrigerator Soup". I have been guilty of adding way more vegetables to this soup.
Carrots, French beans and cabbage are used for the recipe. These crunchy vegetables are a good contrast to the delicate soup.
You can add Broccoli, Peas, Corn or leafy greens like Spinach or Kale.
Coriander Leaves + Stem - Since the soup is all about coriander, both stem and leaves are used.
Note - Substitute Coriander with Cilantro.
If you make vegetable stock or broth at home, include coriander stems. They are packed with flavour.
Ginger + Garlic + Spring onions (scallions) - You can substitute spring onions with regular onions too or use leeks, white onions if you like.
The quantity of ginger and garlic might seem a bit much but it really is essential for a good flavourful soup. Always chop and add them instead of using a paste.
Instead of Water or Stock, you can use Better than Bouillon paste. If using store bought stock, opt for a low sodium one.
Lemon Juice - Extract fresh juice, measure and use for the recipe. Add the juice after you have switched off the gas stove.
If you bulk cook this soup (like me), add the lemon juice only to the portions you are serving and store the remaining in the refrigerator.
Black Pepper Powder + Turmeric Powder - Adds flavor, health and nutrition to the soup.
Did you know that you adding black pepper along with turmeric increases the absorption of curcumin? Source
Variations
If you are looking to include Protein - Add Tofu (plant-based) or Paneer (Cottage Cheese). Beans like Chickpeas or Kidney Beans can be added.
Soba Noodles or any other Gluten Free Noodles can be added for a Lemon Coriander Noodle Soup and turn into a one bowl filling meal.
This soup is NOT SPICY. You could add some red chilli flakes or finely chopped green chillies.
How to Thicken Lemon Coriander Soup?
If you like thick soups, mix 2 tsp of cornflour or cornstarch in 1/4th cup of water. Add after the soup has reduced and just before adding the coriander leaves, lemon juice.
