After 15 minutes' resting time, take a spatula, and gently run it around the edges of the pan, making sure you are also loosening the underside of the cake. Keep shaking the pan as you go, to encourage the loosening process. Place a large plate over the top of the pan- the plate should be bigger than the pan itself- and very carefully, but quickly, flip it over. The cake should slip out onto the plate, with all the little golden apricots facing upwards.
