the original Swiss health breakfast: rolled oats soaked overnight and mixed with plenty of grated raw apple, lemon juice, cream or yoghurt, and nuts, exactly as Dr Bircher-Benner devised it around 1900
Origin: Zürich, Switzerland
From the journey of Oat.
Bircher muesli is the ancestor of every bowl of muesli and every jar of overnight oats in the world, and it was invented, with a doctor's precision, around 1900. Maximilian Bircher-Benner, a Zürich physician and an early evangelist of raw food and fresh fruit, devised it for the patients of his sanatorium after encountering a similar soaked-oat dish eaten by herdsmen in the Swiss Alps. He called it, in Swiss-German, 'Birchermüesli', from muesli, a diminutive meaning 'little mush', and he intended it not as a cereal drowned in milk but as a fruit dish in which the oats played a supporting part. In Bircher-Benner's original the grated raw apple was the main ingredient, the soaked oats a mere binder, and the whole was sharpened with lemon and enriched with a little sweetened condensed milk and chopped nuts. The defining technique is the soak. The rolled oats are not cooked but softened overnight (or for several hours) in liquid, which makes them tender and digestible whilst keeping the raw, fresh character that Bircher-Benner prized; the grated apple, added with its skin, both sweetens the dish and, thanks to the lemon juice, keeps its colour and lends a fresh acidity. Modern versions lean more heavily on the oats and on yoghurt in place of the condensed milk, and add berries, other grated or chopped fruit, and seeds, but the essentials are unchanged: soaked oats, grated apple, lemon, dairy, and nuts, eaten cold. That a grain so long dismissed as fodder should have been reinvented in an Alpine clinic as the very emblem of healthful eating is one of the sharpest reversals in the history of food, and it began in this bowl.
The purest version, close to Bircher-Benner's own, uses a very high proportion of grated apple to oats, lemon juice, and sweetened condensed milk, with the oats soaked only briefly; modern versions use more oats and yoghurt and a longer soak. Other grated or chopped fruit (pear, banana) and seeds may be added, and apple juice in place of some of the milk gives a fruitier result. Use rolled oats, not instant (which turn to paste) or steel-cut (which stay hard even when soaked). This bowl is the direct ancestor of the whole modern genre of overnight oats.
