A delicous cake that takes 5 minutes to make and is a classic favourite –  in Swedish “fika”.

Whisk 3 organic eggs with 150g caster sugar until thick. Meanwhile, melt 75g butter in 75ml water. Add this plus 110g plain flour and 1 1/2 teaspoon baking powder to the eggs and flavour either with half a teaspoon of coarsely ground cardamom – my personal favourite – or the grated rind of one orange. Bake at 175C for 45 min. Eat as soon as possible!
