Pour the flour into a bowl and press a depression into it. Warm 250 ml milk lukewarm. Mix yeast, 100 ml warm milk and 25 g sugar, pour into the bowl and dust with flour. Leave in a warm place for about 10 minutes. Add 150 ml warm milk, 75 g sugar, salt, lemon rind, egg and 100 g soft fat to the bowl rim.

Knead the dough once more and divide into 8 pieces. Press each piece a little bit flat, put plum jam in the middle as a blob. Beat the dough over the plum jam and form into balls. Place the balls close together in an ovenproof dish. Cover and leave to rise for another 10 minutes. Meanwhile melt 25 g fat. Add 100 ml of milk and 25 g sugar and heat gently until the sugar has dissolved. Pour the mixture over the cakes.
