Here is the original swiss recipe for bircher muesli that was developed around the turn of the last century by swiss physician maximilian oskar bircher-benner. The original recipe requires a two-step process. Raw oats are plumped with water in a container overnight. When ready to serve, sweetened milk, grated apple with lemon juice, and chopped nuts are added. It is interesting to note that this original recipe now reflects the modern food guide pyramid recommendations set forth by the usda. Today's idea of muesli has changed over the years to contain a larger portion of oats, less fruit, more grain, more sugar, cream, and dried fruits. And instead of it being a two-step process, "Overnight oatmeal" Was created by folks in a hurryall the ingredients are mixed together and refrigerated overnight ready to be eaten as is in the morning, often on the way to work. This breakfast or snack can be gluten-free if made with certified gluten-free oats (always check your label). The proportions used here will make 1 serving but they easily can be doubled, tripled, or quadrupled to accommodate your family.
