Ingredients

4 tablespoons unsalted butter 

1 large yellow onion, cut into 1/4-inch dice 

2 bunches radish greens (about 2 cups), cleaned 

6 medium baking potatoes, peeled and cut into1/2-inch dice 

4 1/2 cups Homemade Chicken Stock 

1 cup heavy cream 

Coarse salt and freshly ground pepper 

5 radishes, zested 

Chervil, for garnish 

Preparation

In a medium stockpot, melt butter over medium heat. Stir in onions, and saute until transparent, about 4 minutes. Add radish greens, and cook until wilted, about 4 minutes. Add potatoes and chicken stock, and cook, stirring occasionally, until potatoes are tender, about 35 minutes.

Working in batches, pass the mixture through a food mill into a medium bowl. Stir in cream, and season with salt and pepper. Strain the pureed mixture through a fine-mesh sieve into the original pot. Bring soup just to a simmer over medium heat. Serve garnished with radish zest and chervil.
