For the rabbit ears, cook quail eggs hard for 4-5 minutes. Quench and peel. Peel and finely chop the onions. Knead minced meat, onions, mustard, egg, breadcrumbs, salt and pepper.
Divide the mixture into 10 portions. Form each portion into an oblong shape first, then press flat. Place 1 quail egg on the lower half of each portion and cover with chopped mass. Form elongated meatballs, making one end pointed, so that the shape of the rabbit ears is created. Cover and chill for about 15 minutes.
For the salad, peel and coarsely grate carrots, celery and apples. Drizzle the grated apples with lemon juice. Mix apple juice, vinegar, salt, pepper and sugar. Fold in 6 tbsp. oil. Mix the grated apple and vegetables with the vinaigrette, season again.
Bring milk, 1/8 litre water, salt and butter to the boil in a saucepan. Add the flour at once and stir with a wooden spoon until the dough separates as a lump from the bottom of the pot. Stir in 1 egg, allow to cool for 10 minutes, stir in the remaining eggs one after the other10 tablespoons of oil in 2 portions in a large pan. Fry the "chopped ears" in it in 2 portions all around for about 10 minutes. Drain on kitchen paper. Distribute the salad in glasses. Halve the "Hackn.ear" lengthwise. Place 2 halves on each salad.
