Context: Cook until potatoes are thawed and broken apart . Add the vegetable stock and boil for a few minutes until potatoes are very tender . Add the spinach and cook for a few minutes longer , until spinach is just tender . Transfer soup to a food processor , in batches if necessary , and process until relatively smooth ( it does n't need to be homogenous ; the spinach and potatoes just need to be broken up into flecks . ) Return to the pan and add the lentils .

Question: Why do you not have to process the soup until it is very smooth ?
Options:

1. The soup is best when there 's some full consistency to it and there 's still a bite to the dish
2. Soups in general can be too smooth and they do n't taste good
3. Soup when smooth is more like baby food and that 's unappetizing
