The raw oat-and-fruit porridge known as Birchermüesli was invented by Dr. Bircher-Benner, a Swiss doctor who was a pioneer in what we would now call "wellness" medicine, and an advocate of whole foods, exercise, swimming and sunbathing. Now Birchermüesli and its many derivatives are regular breakfast and dessert features at most Swiss tables and around the world. You can use all types of apples or a combination of apples and pears; seasonal berries also make a wonderful addition. For the less health-conscious, a little bit of cream is often stirred into the mix at the end.
