Dissolve the yeast in a little lukewarm milk, let the sugar and salt dissolve in the rest of the milk. Cut the elderflower into small bunches, leaving as little green as possible. Knead everything together to a bread dough and let rise in a warm place for about 1 hour.
Knead again vigorously and fill into two loaf tins. Brush with oil and let rise for another 2 hours. Bake at 200 ° C for about 45 minutes until golden brown.
