In Season: Chill Out with Cool, Miso-Inflected Zucchini Soup!

Summer and zucchini go together like Dizzy Gillespie and his trumpet, Einstein and relativity, Dorothy Parker and snark. Eaten raw right off the vine, lightly steamed, grilled, pickled or pulverized, their mild flavor and chameleon-like ability to mimic their surroundings makes them a ubiquitous choice for summer meals and snacking.

Ridiculously inexpensive to buy and so abundant in the garden that they've earned a reputation for midnight distribution on neighbors' porches, my CSA had a "take all you want" sign over a bin of them at the farmers' market last week. And since I have a hard time not taking advantage of that kind of offer, I came home with several pounds of green, yellow and striped versions.

The blistering heat of the last few days made the idea of turning on a burner a complete non-starter, but I had the good fortune to run across Hetty Lui McKinnon's recipe for a cold zucchini soup—her inclusion of miso definitely intrigued me—involving nothing more than plugging in a blender, plus I had enough of the ingredients to be able to riff on her basic instructions.

With minimal chopping and a few snips of garden herbs, within 30 minutes dinner was on the table and the house was none the hotter for the effort. I'm now secretly hoping for some middle-of-the-night donations to mysteriously appear on my porch (hint, hint).

Chilled Zucchini Soup with Miso

1/2 c. raw cashews
2 c. vegetable stock (or 1 c. chicken stock 1 c. water)
6 Tbsp. lemon juice
2 lbs. zucchini, roughly chopped
1 c. herbs, roughly chopped (I used a combination of parsley, mint, cilantro and lemon basil)
1 c. fennel, roughly chopped
1/2 ripe avocado
3 garlic cloves, roughly chopped
3-4 Tbsp. white (shiro) miso
Salt, to taste
Condiments: Quartered limes, pickled onions, sliced green onions, extra-virgin olive oil

Place the cashews, lemon juice and just 1/2 cup of the stock in the blender or food processor. Blend thoroughly to create a creamy liquid.

Add remaining ingredients to the blender and puree; depending on the size of your blender you may need to work in batches. Adjust salt and lemon.

Three Totally Chill Summer Soups

Looking at the weather forecast for the next few days, and knowing that the dog days of summer (i.e. August in the Pacific Northwest) are just around the corner, I thought I'd get my proverbial ducks in a row ahead of time.

Gazpacho isn't always red…this is made with yellow tomatoes!

Like most of you, the last thing I want to do when the temperature hits 90 degrees or more is to turn on the stove, so I looked up the plethora of chilled soup recipes collected in the archives here at Good Stuff NW and found a few that are going to come in handy sooner than later.

Luckily for us Northwesterners, the summer harvest is coming on strong after our extraordinarily cold, wet spring—that sound carried on the wind is local farmers heaving a big ol' sigh of relief—so the tomatoes, fennel, fruit, peppers and other cooling things you'll need will be in good supply at our local farmers' markets. 

Cucumber, fennel, avocado…

Gazpacho is what most often comes to mind when chilled soups are mentioned (photo at top and above left). A fresh tomato soup made in a blender with other vegetables and a bit of bread to give it body, you can make it ahead of time or right before serving. It's handy to have a jar on hand in the fridge for a quick lunch, appetizer or light dinner with a hearty green salad.

I'm personally in love with Persian cucumbers, the smaller, less seedy version of their big, waxy cousins that we're used to. Many local farms have started growing them for customers who like their size and that they don't have to be peeled and seeded, yet still retain the cucumber's fresh, crunchy flavor and texture. A common featured ingredient in chilled soups, combining them with other seasonal vegetables is a great way to go.

Don't let the garlic scare you…this is a gently flavorful, cooling soup.

A Spanish chilled garlic soup is cool and light with a requisite zing from the garlic and a soothing sweetness from halved grapes. It's the perfect starter to a summer evening in the back yard. It would also be terrific poured into a lidded pitcher and taken on a picnic (or a concert on the lawn) with a rotisserie chicken from the store along with a fruit salad and a bottle of chilled rosé. 

So when it eventually does start to heat up and you feel that cranky demon lurking right around the corner, take inspiration from these three cool customers. With a minimum of chopping and a quick whir in the blender, they'll turn that sweaty frown upside down.

Tomato Gazpacho

Adapted from Julia Moskin's recipe in the New York Times.

Makes a full blender.

5-6 medium tomatoes
1 small Persian cucumber or a small, peeled and seeded regular cuke
1 poblano or Anaheim pepper
1/2 medium onion
2 cloves garlic
1 Tbsp. white or red wine vinegar
1/2 c. extra virgin olive oil
Salt to taste

Cut all the vegetables into rough chunks. In the blender, put in the tomatoes first (they'll liquify quickly and pull in the other stuff) then add cucumber, poblano pepper, onion, and garlic. When that has been puréed, add vinegar and blend until very smooth. With the motor is running, add extra virgin olive oil. Taste and add salt if needed. Chill or serve with ice, and add a little water if it's too thick to drink easily.


Chilled Cucumber, Avocado and Fennel Soup

2 medium cucumbers, peeled and seeded, or 3-4 Persian cukes (no peeling or seeding needed.)
1 avocado, peeled and seed removed
1 fennel bulb, quartered and cored
1/4-1/2 onion, roughly chopped
1 clove garlic, roughly chopped
Juice of 1/2 lemon
1 c. water
1/2 c. sour cream
1, 1" slice day-old artisan bread, crusts removed and cut in 1/2” cubes
Salt to taste

Place half of the cucumbers, avocado, fennel bulb, onion, garlic, lemon, water and sour cream in a blender. Blend until mixture is thoroughly puréed. Add half of bread cubes and continue to blend until it is a smooth mixture. Add salt to taste. Pour into large mixing bowl. (At this point you can taste and adjust amount of onion, etc., for the other half of the soup.) Repeat with second half of ingredients. Stir to combine. Can be refrigerated (or not) before serving.


Sopa de Ajo Blanco

My friend Judy Holloway learned to make this soup when she and her family lived for a time in Spain.

1/2 c. blanched almonds
3-4 slices of large-sized baguette, more if using smaller loaf
3 cloves garlic
1 tsp. salt
4 c. water
5 Tbsp. olive oil
3-4 Tbsp. sherry vinegar
16-20 seedless green grapes

Put slices of bread in water to soak. Peel garlic. While bread soaks, put garlic and almonds in processor or blender and pulse until smooth. Squeeze water from bread, tear into pieces and add bread and salt to blender. While blending slowly, add oil, vinegar and finally water to blender. Taste, adjusting salt, vinegar and oil to taste. Chill at least 2-3 hours or overnight. Serve grapes on side, or put several in soup bowl and pour soup over grapes. Serves 4.

A Gazpacho of a Different Color

Tomato season is at its peak, cucumbers still hang heavy on their vines and peppers of all colors are finally getting the long hours of sun and heat they need to fully ripen their fruit. Cookbook author Nancy Harmon Jenkins posed the perfect solution when I found myself with all those ingredients just the other day:

"What better excuse for a bowl of chilled gazpacho for lunch? Or dinner, or an afternoon snack for that matter? In Andalusia, where this healthy bowl originates, they keep a big pitcher of gazpacho in the refrigerator at all times, ready for anyone who feels the need for a quick pick-me-up."

Peak tomato season means making a big pitcher of gazpacho.

The tomatoes I had from my neighbor Bill's large garden were large and perfectly ripe, begging to be savored fresh rather than cooked, while their juices and flesh were at their sweetest. Bill had also gifted me a cucumber at the same time, and I had a few peppers from my CSA share.

Call me unimaginative, but those perfect tomatoes were golden yellow, so the idea of making a gazpacho was a slap-my-forehead revelation since I'd only had it with the usual red tomatoes. Of course it was divine, and couldn't have better suited the moment. Nancy has a recipe that I'll be trying soon, but here's a slightly simpler version based on Jim Dixon's from years ago.

Tomato Gazpacho

5 to 6 medium tomatoes, roughly chopped
1 small cucumber, peeled
1 mild green chile (Anaheim or, for a little more kick, poblano), seeded and chopped
1/2 yellow onion, roughly chopped
2 cloves garlic
1-2 Tbsp. white or red wine vinegar, to taste
1/2 c. olive oil
Salt to taste

Put tomatoes into the blender. Add the rest of the ingredients and pulse until the ingredients begin to emulsify, stopping to push the tomatoes down if they aren't moving. When they're mostly blended, add the vinegar and salt and blend until very smooth. With the motor running, slowly add the olive oil until completely emulsified. Pour into a glass or ceramic container and chill for one hour. If it's too thick to pour, add a little water, though it should be served fairly thick, not runny.
