I believe every home has a food, or foods, that are staples. These are food items that everyone eats, that move fast and whose presence in the kitchen cupboards or fridge keeps everyone calm because it means there’s food in the house, even if there’s nothing else available.
For some people, the staple is bread. As long as there’s bread, everything is fine. Growing up, this was a staple in our house and we went through four loaves daily. Mum usually bought freshly baked bread on the way home from school, and one loaf would be demolished by the time we reached our gate. The kitchen cupboards could be empty but as long as there was bread, it was generally considered that there was food.
