There are two weeks in July when the cherries come in. Not the sweet black ones you buy year-round from somewhere else, the real ones. Stevnsbaer, the dark sour cherries that grow along the chalk cliffs on the eastern edge of Sjaelland, small and tart and almost black when they're ready. For those two weeks, Danish kitchens smell of cherries and cinnamon and sugar, and one of the things that comes out of all that cooking is kirsebaersuppe.

This is Denmark's answer to summer heat. Where potato soup belongs to the dark evenings of October, cherry soup belongs to the long bright ones of July, when the light doesn't leave until after ten and you want something cold and red and alive on the table. You simmer the cherries gently with cinnamon and vanilla and lemon, thicken the soup with potato starch so it takes on a silky body without losing its clarity, and chill it until it's properly cold. Then you spoon soft whipped cream into the center of each bowl and watch the cream swirl through the ruby like weather.

The one thing I want you to pay attention to is the potato starch. Kartoffelmel is the Danish pantry thickener, and it behaves differently from cornflour. It goes into cold water first, always, and it thickens the soup the moment it touches the heat. Once it's in, the soup can't boil again or the starch breaks down. I'll walk you through the moment so you get it right the first time. The season decides when you make this. The cherries tell you they're ready. You'll know when it's right.

The sour cherries of Stevns, on the eastern coast of Sjaelland, have been cultivated since the 1600s in the chalky soil left behind by the region's prehistoric cliffs, and the Stevnsbaer variety was granted protected geographical status by the EU in 2009. The cherries became internationally famous through Peter F. Heering, a Copenhagen grocer who in 1818 began producing a cherry liqueur from them that would travel the world as Cherry Heering and flavor the original Singapore Sling. Kirsebaersuppe itself belongs to the older Danish and Northern European tradition of fruit soups served as summer desserts, a category that has nearly disappeared from restaurant menus but still survives in home kitchens whenever the cherry harvest comes in.

The technique, the tradition, and the story behind every dish.

Instructions

  1. 1

    Pit the cherries

    Stem the cherries and pit them over a bowl so you catch every drop of juice. The juice is half the color of the finished soup, and you do not want to lose it to the sink. A proper cherry pitter is worth its small price in July. If you do not have one, a chopstick pushed through the stem end works surprisingly well. Keep the pitted cherries and their juices together.

    Wear an apron you don't love. Cherry juice stains, and in July you'll accept it as part of the bargain.
  2. 2

    Build the base

    Put the cherries and their juices into a heavy pot with the cold water, sugar, cinnamon stick, lemon zest, and the split vanilla pod. Scrape the vanilla seeds into the pot as well. Bring everything to a gentle simmer over medium heat, stirring once or twice so the sugar dissolves. Do not boil hard. Hard boiling breaks the cherries into mush and turns the soup muddy. You want a lazy simmer that keeps the fruit whole.

  3. 3

    Simmer the fruit

    Let the soup simmer uncovered for about twenty minutes. The cherries will soften and give up their color, and the liquid will go from pale rose to deep ruby. Taste it. If your cherries are very tart, add a little more sugar now. If they're on the sweet side, leave it alone. Sour cherries want to stay a little sharp. That's what makes this soup refreshing instead of cloying.

  4. 4

    Thicken with potato starch

    Fish out the cinnamon stick, the lemon zest, and the vanilla pod. Mix the potato starch with the three tablespoons of cold water in a small cup until smooth. This is called a slurry, and it matters that the water is cold. Hot water will seize the starch into lumps. Turn the heat down to low. Pour the slurry into the soup in a slow stream, stirring constantly. The soup will thicken within seconds, going from thin liquid to a glossy, lightly bodied soup that coats the back of a spoon.

    Potato starch thickens differently from cornflour. It holds its clarity and gives the soup a silky, almost luminous quality. Once it's in, don't let the soup boil again. Boiling breaks the starch down and the soup will thin back out.
  5. 5

    Add the liqueur and chill

    Take the pot off the heat. If you're using the cherry liqueur or red wine, stir it in now, off the heat, so the alcohol stays bright. Transfer the soup to a large bowl or jug and let it cool on the counter for twenty minutes. Then cover and move it to the fridge for at least two hours. Kirsebaersuppe is a cold soup. It needs to be properly cold, not just cool. The flavor deepens as it chills, and the texture settles into something between a soup and a thin compote.

  6. 6

    Whip the cream and serve

    Just before serving, whip the cold cream with the icing sugar until it holds soft peaks. Not stiff peaks. You want the cream to melt into the soup slowly, not sit on top like a scoop of ice. Ladle the chilled soup into shallow bowls, add a generous spoonful of cream to the center of each, and place a few small rusks on the side. The cream will bleed out in pale swirls across the ruby surface, and that is the whole picture. Tak for mad.

Chef Tips

  • Sour cherries are the point. Sweet cherries make a flat, sugary soup with no backbone. If you can't find fresh Stevnsbaer or morellos, frozen sour cherries are a better choice than fresh sweet ones. The tartness is what makes the soup refreshing.
  • Kartoffelmel, Danish potato starch, is worth seeking out. It gives the soup a glossy clarity that cornflour cannot match. You'll find it in Scandinavian shops or online, and a bag lasts a long time in the pantry.
  • The traditional accompaniment is tvebakker, the small twice-baked Danish rusks that hold their crunch against the cold soup. Almond macaroons work beautifully too. Either way, the contrast between the cold, smooth soup and something dry and crisp alongside is half the pleasure.

Advance Preparation

  • Kirsebaersuppe is made for advance preparation. Make it the morning of a dinner party, or even the day before. The flavor deepens overnight in the fridge as the cinnamon and vanilla settle into the fruit.
  • The soup keeps for four days in the fridge, covered. Stir it well before serving, as the fruit can settle at the bottom.
  • Whip the cream at the last moment. Whipped cream made more than an hour ahead starts to weep, and the effect on the bowl is less beautiful.
