Kiisseli is a very common Finnish dessert that can be made with berries, either with one type of berry, or mixed of several kinds, or even with rhubarb. It's an excellent, easy-to-do, and versatile dessert that can be made all year round with a different variety of healthy berries such as strawberries, raspberries, blueberries, redcurrant, whitecurrant, blackcurrant, lingonberries, cranberries, and cloudberries.
In Finland, kiisseli is usually eaten with porridge/puuro, but it's also good as a dessert/välipala or you could eat it as a light meal too, with nut-muesli or other cereal-breakfasts. It's common in schools and daycares.
3 cups water (about 500ml)
2 cups (about 400g) mixed berries (fresh or frozen)
3 tablespoons potato flour/starch (or corn flour)
3 tablespoons sugar
1. Transfer the berries, water and sugar in a pot, then bring to boil.
2. Mix potato flour and 2-3 tablespoons cold water well in a small bowl with a fork until smooth with no lumps, and while stirring, add it into the berry mixture.
3. Let the soup come to bubble, but not boil entirely, then take it away from the heat immediately. The consistency should be like a thick soup, but not watery or loose.
4. Let it cool, transfer it to a serving dish.The leftover could be placed in a glass jar, and transferred in the fridge for several days.
*For kiisseli, you could use one type of berry, or buy a mixture of fresh berries; raspberry, strawberries, and blueberries are usually the favourites of kids. In the freezer section of supermarkets, you can find ready mix-berry packages or separately to buy and then mix.
*For a healthier sugar-free option, you can add sweet dry fruits ie dates, cut them in small pieces, and then add into the pot. Stir well so that the kiisseli gets uniformly sweet.
*If you have kids, you could also add some fresh strawberries and cinnamon, a classic favorite spice. To make it more nutritious, add the favorite nut/seeds/muesli of your kids to the bowl and create a colorful dish to make it more appealing.
