A cake I always bake during plum season and freeze pieces for later use. When I grew up, plum cake and potato soup was a regular meal. I don't like the dough very thick, so I roll it out really thin and use the rest of the dough for a braid.
Measure milk and sugar. Pour half the milk into a small bowl and stir in some of the sugar, warm milk in microwave - just body temperature. Sprinkle yeast onto milk and stir lightly. Let stand in a warm place until bubbling up. Measure flour into mixing bowl, add salt. Pour milk/yeast mixture into well in middle of flour. Combine some of mixture with surrounding flour. Let stand until more bubbles form. Melt butter and add to remaining milk. Melted butter and cold milk will combine to lukewarm liquid. Add eggs, remaining sugar, lemon zest and milk/butter mixture. Knead about 10 minutes until dough becomes uniform and smooth. Let rise in a warm place for one hour. Roll out dough into a thin rectangle (if too much dough, you can make the rest into a small yeast braid). Place on cookie / cake pan. Cut open plums, remove pits and, while not separating parts, slit plums into four attached quarters. Place closely together, overlapping rows of plums onto dough rolled out on cookie sheet. Sprinkle grated almonds, 30 g butter, cinnamon to taste (or not), and a few spoonfuls of cream. Bake at 200 Degrees Celsius for 45 to 50 Minutes (30 Min. in my oven).
