I first came across Bircher Muesli at Betty's café/restaurant near Harrogate. My version of Bircher Muesli is oats and sultanas soaked overnight in apple juice and then mixed the following morning with fruit, fresh or frozen, or a mix of the two, as well as a good helping of chopped hazelnuts. There are lots of different recipes on the internet, if you are interested and some include honey and yoghurt. Lately I have been using fresh strawberries and raspberries when available, and frozen cherries, blueberries, and raspberries when not. My Polka raspberry canes have produced a good cupful of berries for my breakfast in the morning and although there aren't many, they are healthy and without any sort of insect invasion.
