Drain the apricots, dab dry. Wash the currants, dab dry and remove from the panicle. Beat the eggs, sugar, milk, rum and lemon zest with the whisk of the hand mixer on a hot water bath until the sugar is dissolved.
Then beat cold until a firm cream is formed. Melt butter and add slowly. Mix flour and almonds and fold into the egg-sugar mixture. Grease 4 moulds (18x12.5 cm; 300 ml content) and spread the mixture on top.
Spread the apricots and currants on the dough and bake in the preheated oven (electric range: 175 °C/ gas: level 2) for 40-45 minutes. Remove, dust with icing sugar and serve.
