Danish Sweet Soup: A Cozy Fruit Soup with Tapioca

Danish sweet soup, often called sødsuppe, is a gently spiced fruit soup made with dried fruit and small pearls of tapioca or sago. This flexible Danish-style recipe combines prunes, apricots, raisins, and dried apple in a lightly lemony broth, and can be served warm or chilled as a dessert or simple sweet course.

Ingredients

1/2 cup (75 g) small pearl tapioca, not instant tapioca
1 1/2 cups (360 ml) cold water, for soaking the tapioca
6 cups (1.4 L) water, for the soup
1 cup (150 g) pitted prunes, cut into quarters
1 cup (160 g) dried apricots, cut into bite-size pieces
1/2 cup (75 g) raisins
1 cup (45 g) dried apple rings or slices, roughly chopped
1 cinnamon stick, about 3 inches (8 cm) long
1/4 teaspoon fine salt
2 tablespoons (25 g) granulated sugar, plus more to taste
1 teaspoon finely grated lemon zest and 1 tablespoon (15 ml) lemon juice
1 teaspoon (5 ml) vanilla extract, optional

Instructions

Soak the tapioca. Put the small pearl tapioca in a bowl and cover it with the 1 1/2 cups (360 ml) cold water. Let it stand for 30 minutes, then pour it through a fine-mesh strainer and drain well. Soaking helps the pearls cook more evenly and reduces the chance of a firm center. Check your package, too: some small pearls have different soaking directions. Instant tapioca is not a direct swap for this method.
Start the fruit broth. Add the 6 cups (1.4 L) water, prunes, apricots, raisins, dried apple, cinnamon stick, and salt to a large saucepan. Bring the mixture to a gentle boil over medium-high heat, then lower the heat so it simmers steadily. Partially cover the pan and cook for 18 to 20 minutes, stirring once or twice. The fruit should soften and plump, but it does not need to dissolve.
Cook the tapioca. Stir in the drained tapioca, then return the soup to a gentle simmer. Cook uncovered for 12 to 15 minutes, stirring frequently and scraping along the bottom of the pan so the pearls do not stick. The tapioca is ready when most pearls look translucent and feel tender, with no hard white center. If the soup boils vigorously, lower the heat; a lively boil can break up the fruit and make the liquid reduce too quickly.
Season and finish. Remove the cinnamon stick. Stir in the sugar, lemon zest, and lemon juice. Taste a spoonful and add a little more sugar if your fruit is especially tart, or another teaspoon of lemon juice if the soup tastes too sweet. Stir in the optional vanilla. Keep in mind that the soup will thicken as it stands, so leave it a little looser than your preferred final consistency.
Serve warm or cool. For a warm bowl, let the soup sit off the heat for about 5 minutes, then ladle it into bowls. For a chilled version, cool it promptly in a shallow container and refrigerate it until cold. If the tapioca has thickened the soup more than you like, stir in a splash of water just before serving.

Tips

Use small pearls, not instant tapioca. Small pearl tapioca gives the soup its characteristic soft, gently chewy beads. Sago pearls are the traditional-style alternative when available; they are made from starch and may need a different soaking or cooking time, so follow the package directions. Small pearl tapioca is an accessible substitute and gives a very similar texture. Instant tapioca thickens differently and can turn the broth cloudy or gel-like.
Cut the fruit to a similar size. Quarter the prunes and chop larger apricots and apple slices so each spoonful has a balanced mix. If your dried fruit is unusually firm, give it a quick rinse and simmer it for a few extra minutes before adding the tapioca. Very soft fruit can be added as written, but stir gently so it keeps some shape.
Stir more often after adding tapioca. Tapioca settles and can catch on the bottom of the pan, especially as the soup thickens. Use a broad spoon and stir across the base every minute or two during the final simmer. Keep the heat low enough for small bubbles rather than a hard boil.
Adjust sweetness after cooking. Dried fruit varies in sweetness, and the prunes and raisins already contribute plenty. Begin with the listed two tablespoons of sugar, then taste after the lemon is added. A little lemon helps the fruit taste bright; adding a lot of sugar at the start can make it difficult to balance later.

Serving Suggestions

Serve Danish sweet soup in small bowls as a dessert, a light afternoon treat, or a sweet first course. A spoonful of cold heavy cream, half-and-half, or plain yogurt makes a pleasant contrast to the warm, fruity broth. For a dairy-free option, offer oat cream or coconut cream; coconut adds its own flavor, while oat cream is milder. You can also serve it without a topping, since the fruit and tapioca make each bowl substantial on their own.

The soup works both warm and chilled. Warm servings feel especially comforting on a cold day, while a chilled bowl is refreshing and lets the lemon and dried-fruit flavors come forward. If you plan to serve it cold, make it several hours ahead so the temperature and texture settle. Stir before ladling, and keep a little water nearby to loosen any portions that have become very thick.

Variations

Change the dried fruit. Replace some of the apricots or apple with dried pears, cherries, cranberries, or additional prunes, keeping the total amount of dried fruit close to 3 1/2 cups (about 430 g). Tart cherries or cranberries make the soup sharper, so taste before adding extra lemon. Dates can replace some of the raisins, but they make the broth noticeably sweeter and softer.

Use a different warm spice. Add two whole cloves or a small strip of orange peel with the cinnamon stick, then remove them before serving. A pinch of ground cardamom can also work, but add it sparingly because it can dominate the fruit. For a less spiced version, leave out the cinnamon and let the lemon zest provide the main aromatic note.

Make it without tapioca. If pearl tapioca or sago is difficult to find, leave it out and simmer the fruit until tender for a thinner fruit soup. You can also use 1/4 cup (40 g) small pearl couscous, simmering until tender; this changes the texture from translucent pearls to little pasta pieces. Follow the package timing and add extra water if the broth becomes too thick. These substitutions keep the soup practical, though they will not reproduce tapioca’s particular chewy texture.

Make the sweetness gentler. Omit the added sugar at first and sweeten the finished soup only if needed. For a more pronounced citrus flavor, use a little extra zest rather than a large amount of juice, which can make the broth too sharp. There are family and regional variations of fruit soups, so the mix of fruit, spice, and sweetness can be adjusted to suit what is available.

Storage and Reheating

Cool the soup and refrigerate it within 2 hours of cooking. Store it in a covered container in the refrigerator for 3 to 4 days. Tapioca continues to absorb liquid as it rests, so the soup will be thicker the next day; this is normal. Stir in a few tablespoons of water before reheating, adding more a little at a time until it reaches the texture you want.

Reheat only the amount you plan to serve in a saucepan over low to medium-low heat, stirring often until steaming hot throughout. Avoid a hard boil, which can make the fruit fall apart and the tapioca stick. You can also microwave individual portions in a microwave-safe bowl, stirring every 30 seconds until evenly hot. For food safety, reheat leftovers to 165°F (74°C). If serving chilled, keep the soup refrigerated until serving time and return any uneaten portion to the refrigerator promptly.

For longer storage, freeze the soup in airtight, freezer-safe containers for up to 2 months. Leave a little space at the top because the liquid expands as it freezes. Thaw it in the refrigerator, then reheat gently with extra water as needed. The fruit may soften and the tapioca texture may change slightly after freezing, but stirring while reheating helps bring the soup back together.

Frequently Asked Questions

Is Danish sweet soup served hot or cold?

It can be served either way. Warm soup has a soft, cozy feel, while chilled soup is refreshing and often thickens more as the tapioca cools. Choose the temperature you prefer, and loosen it with a little water if it becomes too dense.

Can I make Danish sweet soup without tapioca?

Yes. Leave it out for a thinner fruit soup, or use small pearl sago if you can find it and follow its package directions. Small pearl couscous is another practical option, but it creates a pasta-like texture rather than the translucent, chewy pearls of tapioca.

Why is my soup too thick?

Tapioca absorbs liquid during cooking and continues to thicken the soup as it cools, especially overnight. Stir in water a few tablespoons at a time until the consistency is right. If reheating, add the water before or during gentle warming so it blends evenly.

Can I use fresh fruit instead of dried fruit?

You can, but fresh fruit contains more water and less concentrated sweetness, so the result will be lighter and less like the dried-fruit version. Use firm fruit such as apples or pears, cut into pieces, and simmer until tender. Taste at the end and adjust the sugar and lemon rather than assuming the dried-fruit quantities will translate exactly.

Can I make it ahead for guests?

Yes. Make it up to 3 days ahead and refrigerate it in a covered container. It will thicken as it chills, so plan to stir in water while reheating or just before serving it cold. Add cream or other toppings at the table rather than mixing them into the pot.

What is the difference between sago and tapioca?

Both are starch-based pearls used to thicken soups and puddings, but sago traditionally comes from the sago palm, while tapioca comes from cassava. They can behave differently in size and cooking time, so check the packet and use small pearls where possible. In this recipe, small pearl tapioca is an easy-to-find stand-in for sago.
