Because it is one of my favorite vegetables, I try to sneak spinach into soup whenever I can. For a delicate soup like this one, the spinach needs to be cooked in boiling water for a minute first. If a relatively small amount of spinach is going into the pot with lots of other ingredients, the whole or shredded leaves can be thrown in as they are—after a careful washing.
Of course spinach can also be used as the focal point of a soup. The following Indian-style recipe is flavored with garlic, onion, and spices, thickened with cooked rice. Spinach soup can also be prepared using potato and leek soup as a base or as a cream soup, using bechamel and heavy cream.
