In an enameled saucepan (in no case in a metal saucepan!!) heat all ingredients except flour and egg yolks leisurely and make 15 min. Now stir flour with water in a cup until smooth and whisk into the cider broth. Make another 5 min. Remove the pot from the fire, add the egg yolks and bring to the table.
In summer, Ebbelwoisupp is also eaten cooled down.
