First preheat the oven to 170 °C convection oven. Then mix all the ingredients together. To make it creamier, the ingredients can also be pureed with a hand blender.
Put the pan in a water bath and bake the curd cake in the oven for 1 hour. If you want the surface to be very soft, simply place a piece of aluminum foil over it.
Allow the curd cake to cool in the pan.
