Steps and mise en place:
Recipe: Sweat the shallots with a little oil, add diced apples and sauté. Deglaze with apple extract and cook until the apples break down. Blend and strain through a fine sieve. Cook the fish in a pan with butter, garlic and aromatics. Heat the apple sauce and add butter to soften its acidity. Finish with chopped parsley. Slice the pike-perch and cover with the sauce.
