This recipe for leek stew, courtesy of Tom Colicchio, is an ideal accompaniment for cornish game hen.
Preheat oven to 350 degrees.
In a medium bowl, mix together pecans, simple syrup, cayenne pepper, fennel seeds, cardamom, pinch of salt, and a pinch of pepper; toss to combine. Spread pecan mixture evenly on a parchment paper-lined baking sheet; bake until toasted and fragrant, about 5. Let cool.
Meanwhile, melt butter in a medium skillet over medium heat. Add leeks and cook until soft. Add potatoes and chicken stock, cook until potatoes are tender, 10 to 12 minutes.
Coarsely chop 1/4 cup of the toasted pecans. Store any remaining pecans for another use in an airtight container for up to 2 weeks. Remove leek mixture from heat and fold in chopped pecans and sage. Season with salt and pepper before serving.
