Peel and cut the blood oranges and cut the wedges into small, bite-sized pieces. Peel and dice the persimmons. Crack and roughly chop the walnuts.
Put the blood orange and persimmon pieces in a bowl and mix with about 1 tablespoon glucose. Add the chopped walnuts and finally sprinkle a handful or more slightly torn cornflakes on top.
A vitamin-rich little snack for in between, also for dessert or as breakfast.
