Sweet Corn Poblano Soup

It doesn’t really feel like summer to me until I’ve had my first ear of sweet corn on the cob. I can eat an outrageous number of buttered, hot, crisp, sweet ears, shearing the kernels off the cob like Mickey and Donald eating it typewriter style.

Fortunately, July hasn’t only brought us a super humid heat wave (hello window AC unit!), it also brought us summer corn season, just in time for the long July 4th weekend.

This light summery soup is a lovely way to enjoy the good fresh flavor of sweet corn. It’s lighter than some creamy chowder style soups,  finished with just a little bit of milk, but the trick of using a corn cob broth that I picked up from David Walbert’s delicious corn chowder post infuses the soup with the flavor of corn without muddling the bright vegetable flavors.

I also use a little bit of corn flour, cooked into the broth like a very thin porridge to thicken the soup without making it too rich and heavy. Soup eaten in summer should be light and fresh, satisfying without weighing down.

Sweet Corn and Poblano Soup

4 ears sweet corn on the cob, husked and flossed

1 red onion (or other sweet onion)

2 cloves garlic

1 poblano chile

olive oil

1/3 cup corn flour

1/4-1/2 teaspoon chipotle chile powder

1/2 teaspoon ground coriander

3/4 teaspoon ground cumin

4 cups water

salt

1 cup milk

Stand each ear of corn stalk-side down on a cutting board and cut the kernels from the cob. Break the cleaned cobs in pieces and put them in a medium pot. Once all of the corn kernels are cut off the cobs and the cobs are put into the pot, cover the cobs with about 4 cups of water, a generous pinch of salt, and cover the pot with a heavy lid. Simmer the cobs in water for about 30 minutes. Remove and throw the cobs away.

Meanwhile, dice the onion and poblano and mince the garlic.

Heat a generous glug of olive oil in a large skillet or saute pan over medium/low heat. Add the onion, garlic and poblano to the oil and cook until the onion begins to soften and become translucent. Add the corn and stir, then add a pinch of salt. The sugar in the corn will begin to stick and caramelize on the bottom of the pan, so watch the heat to prevent that sugar from burning. Once the corn begins to soften, scrape the vegetables to the side of the pan and pour in a little more oil, maybe a teaspoon, to cook the spices. Pour the chipotle, coriander, and cumin into the oil and stir. Once the spices become fragrant, stir them into the vegetables. Scrape any sticky browned bits off the bottom of the pan.

Once the corn is softened and beginning to caramelize  but still a little bit crisp, stir about 1/3 cup of corn flour (finely ground corn meal) into the vegetables. Stir everything over medium heat just for a minute until the corn flour is slightly toasted.

Carefully pour the corn cob stock into the pan with the vegetables and stir to prevent lumps. Bring to a simmer and stir until the corn flour thickens the broth. Add the milk and simmer for 10 minutes or so to combine the flavors.

Salt to taste.

As with most soups, this one improves after a night in the fridge, so feel free to make it ahead. It will be even better that way.

A note on corn flour:

Corn flour is just a finely ground corn meal. In the UK, corn flour is the term used for what I call corn starch which is often used to thicken clear sauces. American corn flour is a little more substantial but finer than the grittier texture of corn meal. I typically use Bob’s Red Mill Corn Flour

Okra Part 2: Maque Choux

My last post was for okra cooked whole, a good way to enjoy okra without any of the “slime” factor. Once you cut into okra, like aloe vera, the mucilage starts to seep out. Adding liquid for a braised or stewed dish enhances this seepage. There are a lot of tricks and techniques that people say will prevent this from happening – cut it in thin slices, cut it as little as possible, sear in with high heat, don’t add any liquid, just to name a few.

 My approach is to just go with it: okra contains mucilage, mucilage is slimy, so rather than try to change the nature of okra, I try to make this quality work for me. Okra is commonly used in gumbo as a “thickener”, a term which I don’t think is entirely accurate, or maybe just isn’t the most complete or descriptive term for what okra does for gumbo. I would say that it adds body to the broth.

 I’ll explain what I mean in terms of chicken stock: good gelatin-filled stock slips over the tongue silkily and substantially, filling the mouth with the essence of its ingredients, rich but never greasy.  The richness of a good homemade stock is not from fat but from the cartilage that has been slowly broken down and infused into the liquid. Okra has much the same effect, not creamy or thick, but lip-smacking.

 Gumbo is the obvious and most common way to take advantage of okra’s bodyfying qualities. I have, however posted a couple of gumbos here on the blog, so I’ll branch out and share another favorite: maque choux (mok shoo). Maque choux is like a succotash where the lima beans are replaced by okra. It is a fresh braise of corn, okra, tomato, onion, and peppers. The crispness of corn kernels and acidity in the tomatoes balance the tenderness of the okra. So to make a silky braised okra dish, balance the proportions of ingredients so that the okra doesn’t overwhelm the rest of the vegetables, add some acid (tomatoes), and cook the dish just long enough to get through the slimy stage to a richly flavored but light bright vegetable dish. It’s a perfect summertime side dish for fish or fried chicken (and yes, I know it’s September, sorry. Check back next year?)

 One of the tricks I use for this dish, I picked up from David Walbert’s brilliant chowder recipe: *after stripping the kernels, break the cobs in half and just barely submerge them in a pot or water. Cover the pot and bring it to a simmer for about 20 minutes, or about as long as it takes to prep everything else. All of the flavor that was left in the cob will infuse the water to make the corniest broth you’ve ever tasted. I prefer not to add a lot of water when I cook vegetables, but with all of the natural sugar in the vegetables, it can get pretty thick and sticky. The corn broth adds nice flavor and loosens up the mixture with out watering down the vegetables.

 Also of note: green bell peppers are probably the traditional choice for this dish. I just prefer almost any other pepper to green bells. I don’t think they have a lot of flavor and I also prefer a little heat, so I usually use a combination of poblano and serrano chiles. If you like other varieties better than the ones I use, they will work perfectly well. Feel free to improvise.

And a final note: if you live somewhere where it is difficult to find okra, this one will work very well with frozen okra. I like to get pods frozen whole and cut them up myself, but sliced is fine.

 

Maque Choux

serves 4

2-3 tablespoons oil (or half oil and half bacon grease, if you’re so inclined)

1 medium white onion, diced

2 poblano chiles, diced

1 serrano chile, minced

2 cup sliced okra

3 ears of corn, kernels removed, cob reserved for broth

2 cups diced tomato with their juice

*Corn broth as needed

Salt

Cayenne pepper if desired

Prepare all of your ingredients and start the corn broth.

In a large sauté pan or skillet, heat the oil and or bacon grease until it shimmers. You need just enough oil to coat the bottom of the pan.  Add the onions and chiles and a pinch of salt and sauté until they begin to soften and become fragrant, 5-7 minutes. Add the okra, tomatoes, and corn and another pinch of salt, which will help the vegetables release their water and keep them from sticking as much. Cover the pan and let it simmer over low heat, stirring occasionally; the okra will start to look “stringy”but the acid in the tomato juice will begin to break that down and melt it into the sauce. Add about ½ cup of corn broth at a time if the vegetables begin sticking to the pan. Once the okra no longer looks stringy, taste test to see if the vegetables are tender. It will probably take 15 minutes or so, but the main thing is to get them past the stringy stage with enough liquid in the pan to make it a loose but not soupy mixture while removing them from the heat before the vegetables become mushy. Salt to taste and add a pinch of cayenne if you like it spicy.
