Ingredients

3 tablespoons unsalted butter 

6 corncobs, reserved from Gnudi with Roasted-Corn Sauce, broken into pieces 

2 celery stalks, coarsely chopped 

1 carrot, coarsely chopped 

1 large onion, coarsely chopped 

1 jalapeno chile, halved lengthwise 

4 garlic cloves, crushed 

7 whole black peppercorns 

4 sprigs fresh flat-leaf parsley 

2 sprigs fresh thyme 

10 cups water 

Preparation

Melt butter in a stockpot over medium-high heat. Add corncobs, celery, carrot, onion, jalapeno, garlic, peppercorns, and herbs, and cook, stirring often, for 10 minutes. Add water, and bring to a boil. Reduce heat, and simmer 45 minutes.

Pour through a fine sieve, pressing on solids to extract as much liquid as possible. Discard solids. Stock can be refrigerated in an airtight container for up to 3 days or frozen for up to 1 month.
