Fill the Maoam crackers (leave out the Cola crackers) in a clean bottle with a capacity of approx. 1.5 liters. Pour the grain over it, close the bottle tightly and put it in the refrigerator for three days. The bottle should be turned twice a day so that the crackers dissolve well.
After the three days, pour the mixture into a large container, pour the blood orange juice over it and stir everything vigorously. Strain and bottle.
