Fresh corn and curry are a favorite combination of mine, and for years I have made a quick blender soup using frozen corn and boxed stock. It’s such a treat for me, that I figured I ought to work out a proper recipe using a full complement of the beautiful summer corn I find at the farmers market. And I love this version even more. Softened with leeks, redolent with corn flavor and a healthy dose of curry powder, this beautiful yellow soup is a perfect summer bowl. Just a few ingredients create a remarkably complex and rich flavor.
I love the base of fresh corn stock, and it is easy to make. You could use vegetable broth for a shortcut, but make sure you use one that is light in color so you don’t muddy the final result. The chewy, toasty corn kernels make a wonderful topping, but get as creative as you want. I could see toasted coconut shards or roasted, salted cashews as a nice contrast. You could add a dollop of yogurt as well. This soup freezes really well, so make a big batch (or several) with in-season corn to stock up for the winter. I love this soup warm, but it is lovely served chilled in the heat of summer.
- 8 ears corn
- 2 large or 3 medium leeks
- 4 green onions
- 2 cloves garlic
- 3 teaspoons curry powder
- 1 teaspoon salt
- ½ teaspoon garam masala
- Fill a large bowl or the sink with cold water and ice. Bring a large stockpot full of water to a boil. Blanch the corn in the boiling water for 30 seconds and remove it immediately to the ice water bath to stop the cooking. When the corn is cool enough to handle, cut the kernels off the cobs into a large bowl. Scrap the cobs to release any juices. Cover the bowl with a tea towel and place in the refrigerator.
- Cut the corn cobs in half and place in a large stockpot (if you use the pot you blanched in, rinse it well to remove corn silks) and cover with 10 cups of water. Bring the stock to a boil, skim off any scum that rise, reduce the heat to medium and simmer, uncovered, for 1 ½ hours. The liquid should reduce by about half. Pour the stock through a strainer and discard the solids.
- Cut the white and pale green parts of the leeks in half, then into thin half-moons. Rinse the pieces thoroughly with cold water to remove any dirt or grits. Rinse out the stockpot and add the olive oil. Cook the leeks, with a little water clinging to them, over medium heat until soft and glossy, about 10 minutes. Stir frequently and do not let the leeks brown. Add the garlic and cook a further minute, then sprinkle over the curry powder, salt and garam masala. Cook, stirring well, for a few minutes until the spices are toasty and fragrant. Measure out 1/2 cup of corn kernels and set aside, then add the rest or the corn and any accumulated liquid to the pot. Stir to combine the leeks and corn, then pour in 4 cups of the corn cob stock and 2 cups water. Bring to a boil, reduce to medium low and cover the pot. Simmer the soup for 30 minutes, until the kernels are very soft. Leave the soup to cool a little, then carefully puree it in batches in a blender. Pour each batch through a fine mesh sieve set over a large, pressing the liquid through. Rinse out the pot again, and return the smooth soup to it. At this point, you can refrigerate the soup for up to 2 days.
- Toast the reserved in a dry skillet until browned and beginning to make a popping noise. When toasted evenly, transfer to a plate so the kernels don’t continue cooking.
- The soup can be served chilled, or warmed through over medium heat. Serve topped with toasted corn.
- Corn stock is a wonderful thing to have around, it pumps up the flavor of a winter chowder made with frozen corn or any vegetable soup. Make big batches and freeze. I keep a Ziploc bag in the freezer and add a striped cob everytime I use corn. When I have about a dozen cobs, I make stock.
