Finnish fruit soup is a gently thickened dessert made by simmering dried fruit with water, sugar, and warm spices; it is often served chilled, though it can also be enjoyed warm. Finnish and other Nordic households have their own combinations, but this version balances prunes, apricots, raisins, and apples for a fragrant, spoonable fruit compote.
Ingredients
- 8 cups (1.9 L) water
- 1 cup (160 g) pitted prunes, halved if large
- 1 cup (150 g) dried apricots, quartered
- 1/2 cup (75 g) raisins
- 1 cup (85 g) dried apple rings, cut into bite-size pieces
- 1/3 cup (67 g) granulated sugar, plus more to taste
- 1 cinnamon stick, about 3 inches (7.5 cm) long
- 1 strip lemon peel, about 2 by 1 inches (5 by 2.5 cm), with as little white pith as possible
- 1/8 teaspoon (0.7 g) fine salt
- 2 tablespoons (16 g) potato starch, also called potato flour in some stores
- 1/4 cup (60 ml) cold water, for mixing with the starch
- 1 tablespoon (15 ml) fresh lemon juice, optional, to brighten the finished soup
Instructions
- Prepare the fruit. Measure the water and sugar, then cut the larger dried fruit into pieces roughly the size of a generous bite. Check the prunes for pits even if the package labels them pitted. If the apple rings are especially firm or leathery, cut them smaller so they soften at a similar pace to the other fruit. This preparation takes about 15 minutes, depending on how much chopping is needed.
- Start the simmer. Pour the 8 cups (1.9 L) water into a large, heavy-bottomed saucepan. Add the prunes, apricots, raisins, apple, sugar, cinnamon stick, lemon peel, and salt. Bring the mixture just to a boil over medium-high heat, stirring once or twice to dissolve the sugar. As soon as it boils, lower the heat so the liquid simmers gently rather than bubbling hard.
- Cook until tender. Simmer uncovered for 18 to 22 minutes, stirring occasionally and scraping the bottom of the pan. The fruit should be plump and tender, with the apples soft enough to cut easily with a spoon, but the pieces should still hold their shape. If your dried fruit is unusually dry, continue simmering for a few minutes and add a splash of hot water if the pan looks low on liquid. Remove the cinnamon stick and lemon peel.
- Make the starch slurry. In a small bowl, whisk the potato starch into the 1/4 cup (60 ml) cold water until smooth. Do not add dry starch directly to the hot soup; it can form stubborn lumps. If the slurry has been sitting for more than a minute, stir it again just before using because the starch settles quickly.
- Thicken the soup gently. Take the saucepan off the heat. While stirring the fruit and liquid in a steady circle, pour in the slurry in a thin stream. Return the pan to low heat and stir for 1 to 2 minutes, just until the soup looks glossy and lightly thickened. Avoid a prolonged boil after adding potato starch, which can make the texture thinner again. The soup will thicken a little more as it cools.
- Adjust and cool. Taste a spoonful once it is cool enough to sample safely. Stir in the optional lemon juice if you want a fresher, less sweet finish; add a little more sugar if your fruit is particularly tart. Let the soup cool at room temperature for about 20 minutes, then transfer it to a covered container and refrigerate for at least 2 hours before serving chilled. Refrigerate it within 2 hours of cooking.
Tips
- Choose fruit by texture as well as flavor. Look for dried fruit that is pliable rather than rock-hard. Very dry fruit takes longer to soften and can absorb more of the cooking liquid; add hot water a little at a time if the soup becomes too concentrated before the fruit is tender.
- Sweeten at the end if needed. Dried fruit varies in sweetness, and some packaged mixes contain added sugar. The measured sugar gives a gently sweet result, not a syrupy one. Start with the amount listed, then taste after cooking and add sugar in small increments if you prefer a sweeter dessert.
- Use cold liquid for the slurry. Potato starch needs to be dispersed in cold water before it meets the hot soup. Whisk thoroughly, stir the soup as you pour, and keep the final heating brief. If the soup is thinner than you like, make a little extra slurry and repeat rather than tipping dry starch into the pan.
- Substitute thoughtfully. Potato starch is traditional in many versions and gives a clear, delicate finish. Cornstarch works if potato starch is hard to find: use 2 tablespoons (16 g) mixed with the same amount of cold water, but expect a slightly more opaque, softer-set soup. Potato flour and potato starch are not always the same product, so check the label for starch.
Serving Suggestions
For a classic dessert, serve the soup cold in small bowls, with some of the fruit and liquid in each portion. A spoonful of softly whipped cream, a splash of pouring cream, or a little plain yogurt makes a pleasant contrast to the fruit. If serving guests, chill the soup thoroughly and add the dairy at the table rather than stirring it into the pot; that keeps the soup’s glossy appearance and lets everyone choose how rich to make the bowl.
It also works warm on a cold day. Reheat a portion gently in a small saucepan, stirring so the fruit does not catch on the bottom, and stop once it is steaming; a hard boil is unnecessary. Serve it as a light dessert after a meal, or offer a small bowl alongside simple cookies or crisp rye biscuits. If the chilled soup has thickened more than you want, loosen each serving with a spoonful of cold water or fruit juice and stir gently.
Variations
There is no single fixed fruit mix for Finnish fruit soup. Dried-fruit blends sold for holiday cooking are convenient, but a homemade mix lets you choose the balance. Replace some or all of the apple with dried pears, use dried cherries for a sharper note, or add a few dates for a rounder sweetness. Keep the total dried fruit close to 12 ounces (about 340 g) so the liquid-to-fruit balance stays similar. If a mix includes very small berries, add them during the last 10 minutes so they do not disappear into the soup.
For a warmer spice profile, add one or two whole cloves or a small piece of star anise with the cinnamon, then remove them before thickening. Use spices sparingly; they should perfume the fruit, not cover it. A small strip of orange peel can replace the lemon peel for a softer citrus aroma, while the optional lemon juice remains useful if the final taste needs a little lift. For a less sweet, more fruit-forward bowl, reduce the sugar to 2 tablespoons (25 g) and add more only after tasting.
If you want a looser compote rather than a spoon-coating soup, use 1 tablespoon (8 g) potato starch with the listed cold water. For a thicker, more pudding-like consistency, add starch cautiously in small increments; the mixture firms as it chills, so do not judge the final thickness while it is piping hot. You can also leave the starch out for a clear, brothy fruit compote, though that will be less like the lightly thickened soup many cooks expect.
Storage and Reheating
Cool the soup promptly and refrigerate it in a covered container within 2 hours of cooking. It keeps for 3 to 4 days in the refrigerator. Store it without cream or yogurt mixed in, since dairy is best added to individual servings. The fruit may settle and the starch-thickened liquid may become firmer as it chills; stir gently before serving, and loosen with a little water if needed.
To serve it warm later, reheat only the portion you plan to eat in a saucepan over low heat, stirring frequently until steaming. Avoid a prolonged boil, especially because potato starch can lose some of its thickening power with extended boiling. If reheating a larger batch, warm it gently and stir from the bottom so the fruit heats evenly. You may freeze the soup in an airtight, freezer-safe container for up to 2 months, though the fruit can become softer and the texture may separate slightly after thawing. Thaw overnight in the refrigerator, stir, and warm gently or serve chilled.
Frequently Asked Questions
What is Finnish fruit soup called?
Names and recipes vary. A Finnish dried-fruit soup may be described as a dried-fruit soup or compote, and holiday versions often use a mix of dried fruits. The exact name, fruit selection, sweetness, and thickness can differ between households and regions, so this recipe is one practical version rather than a claim to a single definitive formula.
Can I make Finnish fruit soup with fresh fruit?
You can, but fresh fruit releases more water and softens faster, so the result will have a different texture and flavor from a dried-fruit version. For a similar style, use firm fruit such as apples or pears, cut it into chunks, and begin checking for tenderness well before the 18-minute mark. Taste before sweetening, since fresh fruit can be more or less tart than dried fruit.
Do I need to soak the dried fruit first?
No soaking is required for this recipe. The fruit softens in the simmering water, which also becomes the soup’s flavorful liquid. If your fruit is unusually hard, you can cover it with the measured water and let it stand for 30 minutes before cooking, but that is an optional adjustment and adds 30 minutes to the total time.
Why is my soup lumpy or too thin?
Lumps usually form when starch is added dry or the slurry is not smooth. Always whisk it into cold water first and pour it into the hot soup gradually while stirring. If it is too thin, let it cool before deciding whether to add more starch; it thickens as it chills. If it remains loose, stir in a small additional cold slurry and heat briefly without boiling hard.
Can I use a store-bought dried-fruit mix?
Yes. Choose an unsweetened mix if possible, and check that the total amount is close to the 12 ounces (340 g) used here. If it contains large pieces, chop them so they cook evenly. Some mixes include fruit that is already very soft, so begin checking the pot around 15 minutes and remove the pan from the heat as soon as the pieces are tender.
Is Finnish fruit soup served hot or cold?
Both are good options. Chilling gives the soup a more set, dessert-like consistency and makes it easy to prepare ahead. Warm servings feel more like a comforting fruit compote. If you serve it warm, heat it gently and avoid a long boil after thickening; if serving it cold, allow at least 2 hours in the refrigerator for the flavor and texture to settle.
