Peel the fruit (either one variety or mixed), cut into small pieces and, if necessary, drizzle with lemon juice. Mix all other ingredients in a bowl to form a smooth batter. Mix in the fruit and pour the mixture into a greased pan (pie form or springform pan, 28 cm in diameter) dusted with breadcrumbs.
Bake at 180 ° hot air for about 40-50 minutes.
I usually serve the fruit cake lukewarm with vanilla ice cream and whipped cream.
