Remove the bottom from the mould. Cut a thin lid off the bottom and crumble it. Set aside covered. Roast the almonds in a pan without fat until golden brown, take them out and let them cool down. Place the cake ring around the base. Drain the apricots in a sieve and puree them finely in a high container with a blender
