Sieve the flour into a bowl, make a hollow in it. Pour the dry yeast into the well, mix with a few tablespoons of the measured milk and a teaspoon of sugar. Cover and let stand in a warm place until the pre-dough forms bubbles.
Then knead with the other ingredients for the dough. Cover again and let rise for at least 45-50 minutes.
In the meantime, beat the egg whites with the sugar until stiff, fold in the almonds and cinnamon.
Knead the dough briefly again, roll out into a rectangle. Brush with the almond paste, roll up from the long side of the rectangle. Cut the roll lengthways (except for a short remainder on one side that holds the whole thing together) twice, so that 3 strands are created. Then braid them into a braid.
Place on a baking sheet lined with baking paper, cover and let rise again and in the meantime heat up the oven to 160 ° C (convection).
When the temperature is reached, put the tray in the oven and bake for 45 minutes.
Toast the almond flakes in a pan to decorate.
Make a glaze from the other ingredients, brush the still warm braid with it and then sprinkle the almond flakes on top.
Attention: The braid opens up gigantically and becomes a real monster, you can bake two smaller braids out of it instead.
