Wash the cherries, drain well and stone them. Separate the eggs for the sponge mixture. Beat the egg whites until stiff and finally pour in 25 g sugar. Cream fat, remaining sugar, lemon peel and salt.
Stir in the egg yolks one after the other. Alternately add flour and milk. Carefully fold in the beaten egg white. Put the dough into a greased springform pan sprinkled with breadcrumbs and smooth it down. Sprinkle with cherries.
Warm the apricot jam, pass it through a sieve and brush the cherries with it. Bake in the preheated oven, 2nd shelf from below (electric oven: 175 °C/ gas: level 2) for approx. 60 minutes. Cover for the last 10-15 minutes.
Let the cake cool down and serve thickly dusted with icing sugar. Whipped cream tastes good with it.
