For the wine soup with rolled barley, soak the rolled barley in water the night before.
The following day, boil in water for 2-3 hours until soft.
Add raisins, lemon peel grated and cinnamon and cook for another hour.
Add wine, sugar and a little salt. Remove from heat and add egg yolk.
If the wine soup with rolled barley is too thick, add a little boiling water.
