Sernik na zimno is the favourite cake of the Polish summer, a no-bake curd cheese cake set with gelatine, its freshness coming from blueberries and lemon. This version is made with low-fat curd cheese and Greek yogurt, so it is lighter than the traditional one. It takes half an hour of work, the fridge does the rest, and it is an ideal dessert for hot days.
Lay the sponge fingers in the bottom of a 22 cm tin lined with film.
Soak the gelatine in 5 tbsp cold water, then dissolve over low heat.
Blend the curd cheese with the yogurt, sweetener and lemon juice until smooth and stir in the lukewarm gelatine.
Fold in half the blueberries, spread in the tin and scatter the rest on top.
Chill for at least 4 hours; it keeps 3 days.

Tips
Always stir the gelatine into the cream while lukewarm, because in a cold cream it sets into lumps at once.
Use frozen blueberries only when fully thawed and drained, because too much juice stains and thins the cream.
Line the tin with film, so that the finished cake lifts out easily and its edge stays neat.
Frequently asked questions
Can the gelatine be replaced?
Yes, with agar-agar, but it sets differently: it has to be boiled, and the amount should follow the packet instructions. The texture will be slightly firmer.
What other fruit can I use?
Strawberries, raspberries or peaches. Do not use fresh pineapple or kiwi, because their enzymes stop the gelatine from setting.
