Sure, you can buy corn year-round, but the yellow imposters found in the dead of winter are completely flavorless. We recommend taking full advantage of the late-summer bounty by turning it into stock, which you can freeze and savor for as long as humanly possible. This stock is great for to use as a base for soup and chowder, thinning out sauces and for adding flavor to rice by cooking it in the broth.

We purée corn kernels and throw them into our stock to pack in even more corn flavor. Spices such as toasted black peppercorns and coriander seeds add complexity, but the most flavorful component in this stock is the charred yellow onion. We’re talking about a deep, beautifully blackened char that fills up your kitchen with that bittersweet caramelized onion scent.  

Aside from what you put into your corn stock, it is also important how you make your stock.  Don’t rush it; go low and slow. Once the stock is at a rolling boil, lower to a gentle simmer and watch it slowly and gracefully turn into something magical.

How to Make Corn Stock

Recipe from the Tasting Table Test Kitchen

Yield: 8 cups

Prep Time: 15 minutes

Cook Time: 2 hours

Total Time: 2 hours and 15 minutes


4 (2½ pounds) corn on the cob, husked

10 cups water

1 tablespoon black peppercorns, toasted

1 tablespoon coriander seeds, toasted

6 parsley stems

2 celery stalks

2 bay leaves

1 garlic clove, smashed

½ yellow onion, halved and deeply charred


1. Shave the corn kernels off the cobs and add the cobs to a heavy-duty stock pot. In a blender, blend half of the corn kernels on high and add to the pot. Save the other half of the corn kernels for other uses.

2. Add the remaining ingredients to the pot and bring to a rolling boil over high heat. Once at a boil, lower the heat to a gentle simmer and cook for 2 hours. Strain the stock and allow it to completely cool. Store in the refrigerator for up to 1 week or freeze in small batches and thaw as needed.
