“My friend Jan once drunkenly asked me to cook for his dad Anton’s 70th birthday, which I enthusiastically agreed to (I was also tipsy). Anton, aka Papa Florek or P Flo, grew up in Derby – his Polish father, Alfredo, had settled there after the war, when he was demobbed from the Carpathian Lancers.

Sernyk, a traditional cheesecake eaten across Poland and Ukraine, was one of Anton’s childhood favourites, something that connected him to his Polish heritage, so I decided that’s what I would make. Struggling to find good-quality cottage cheese the day before, I panicked and bought ricotta, adapting my mum’s original recipe to suit the moister texture of ricotta. It was a huge success, and this cake is now also one of my son’s favourites. I hope someone will make it for him when he is 70.”

Serves: 8-10
Takes: 1 hr


200g unsalted butter, softened, plus extra for the tin
200g apples, cored and sliced
1 tbsp brown sugar
200g golden caster sugar
3 eggs, separated
1 tsp vanilla extract
500g ricotta or good-quality cottage cheese
120g fine semolina or polenta


  • Melt 25g of the butter in a frying pan over a medium heat, add the apples and cook for 2-3 mins on each side until they start to turn golden. Sprinkle in the brown sugar and cook the apples for another minute on each side, then transfer the caramelised apples to a bowl and let them cool slightly.
  • Heat oven to 200C, 180C fan, gas 6 and grease a 20cm square or round cake tin with butter. Lay the apples in the base of the cake tin.
  • Put the remaining butter into the bowl of an electric mixer fitted with the whisk attachment, along with 150g of the caster sugar, and whisk until it’s looking fairly fluffy. Break the egg yolks with a fork and gradually add them, whisking well, then whisk in the vanilla extract and cheese. Transfer the mixture to another bowl, then fold in the semolina or polenta (the latter will result in a cake with more texture).
  • Wash and dry your mixer bowl and whisk attachment thoroughly, then put in the egg whites and whisk until they start frothing up. Add the remaining 50g caster sugar and the salt and keep whisking until you have soft peaks.
  • Take a tablespoon of the egg white mixture and fold it quite vigorously into the butter and cheese mixture to loosen it. Add the rest of the egg white mixture and fold in gently.
  • Pour the mixture over the apples in the cake tin and bake for 30 mins, or until it’s a little wobbly, but not liquid (remember, it will set more firmly as it cools).
  • Leave the cake in its tin to rest and cool down, then slice and serve. Unsweetened tea with lemon is a perfect accompaniment.
