Birchermüesli

Raw rolled oats soaked overnight in milk and lemon juice with grated apple, nuts and a swirl of yogurt.

Birchermüesli was created around 1900 by Swiss physician Maximilian Bircher-Benner for patients at his Zurich clinic, as part of a diet emphasizing raw fruits and vegetables, which was considered unusual and even radical at the time in a culture accustomed to heavy cooked meals. His original version used far less oats and far more grated apple than the sweetened, granola-heavy commercial "muesli" that later spread internationally, and Bircher-Benner intended it as a health food rather than a breakfast cereal in the modern sense.

The original recipe is dominated by grated apple rather than oats, soaked in a small amount of condensed milk and lemon juice, and finished with a spoon of cream and chopped nuts — it is meant to be tart and fresh, not heavily sweetened.
