Notes
Red Lentils: These are perfect for soup as they break down and cook relatively faster than other legumes.
Spices: You can adjust the quantity of spices as per your liking.
Lemon juice: This recipe calls for very few ingredients, and lemon juice plays a key role in lifting the flavors of the soup. I highly recommend using freshly squeezed lemon juice.
Hand blender: I use a hand blender for convenience, but you can also use a blender.
Storing: It can be stored in an airtight container in the fridge for up to 3 days. Freeze up to 1 month.
