Sorrel & Potato Soup
The recipe below is adapted from a classic French sorrel soup recipe. It is also good cold, particularly with some plain yogurt swirled in. Serves 3 or 4.
1 bunch fresh sorrel
4 cups water
Salt and freshly ground black pepper to taste
2/3 pound potatoes, cubed
1 large egg
1/4 cup crème fraiche or heavy cream (or more to taste)
Wash the sorrel and de-rib the leaves if necessary. Put it in a saucepan over low heat. Cook, stirring, until the sorrel has melted into a purée and nearly all of its liquid has evaporated. Add the water and salt and pepper to taste. Bring to a boil. Add the potatoes and cook over low heat until the potatoes are cooked through — about fifteen minutes. If you prefer a creamy rather than a chunky soup, put the soup into a blender or food processor and then return to the saucepan. Combine the eggs and crème fraiche in a warmed serving bowl. Mix until well blended. Add a ladle of the potato and sorrel mixture and blend well. Pour in remaining potato and sorrel mixture and serve immediately.
