Several years ago, my sister introduced me to possibly the most delicious broth I’d ever tasted. The recipe was from The Cancer Fighting Kitchen, by author and chef Rebecca Katz
. Our mother was ill with cancer, so my sister simmered large vats of this delicious stock as we worked to produce palatable and nourishing offerings. The resulting broths developed a deeply layered and satisfying flavor that’s hard to describe. The soup did not cure our mother, but it did nourish her — and all of us, during the hardest period of our lives.
Recently, on a gray and damp day, I made a batch of soup inspired by another Rebecca Katz recipe. This one uses vegetable broth and is full of healthy greens, with lemon zest and pepper flakes for pop and potato for creaminess. I added juice from a lime as well to increase that tart zesty flavor. Once done, I contemplated the emerald green liquid in a bowl. I took a sip, expecting something “healthy tasting.” Instead, I was greeted by a burst of bright flavor, one that evoked springtime and sunshine.
The soup is easy to make. The original recipe calls for collards and green chard. You can also easily add or replace with kale, spinach or any other green you prefer. Rebecca Katz’s recipe also calls for her “Magic Mineral Broth
,” a fantastic vegetable stock recipe for the more ambitious. In this version, I use store bought vegetable broth, which is completely acceptable. Delicious, in fact.
Warm the olive oil in a Dutch oven or other soup pot. Add the onion, potato and 1/4 teaspoon of salt and sauté about 10 minutes. Add the garlic and red pepper flakes and stir for another 30 seconds. Pour in 1/2 cup of the broth, stirring to loosen any bits stuck to the pot, and cook for a few minutes.
Add the collard greens, chard, kale and another 1/4 teaspoon of salt to the pot. Stir well to combine so that the greens begin to wilt. Then add the remaining broth, bring to a boil, reduce the heat to medium, cover, and simmer for 5 minutes.
In a blender, puree the soup in batches until very smooth, each time adding the cooking liquid first and then the greens mixture. (Or, use a hand mixer if you prefer.) Blend the parsley into the last batch.
Pour the soup back into the pot, heat gently, and stir in the lemon zest and juice, as well as the lime juice. Taste and serve!
