In ancient Rome, kitchens were equipped with a unique built-in fruit and vegetable storage system called a 'horreum'. A horreum was a large, underground storage facility that was used to store various food items, including fruits and vegetables. These storage facilities were built with thick walls and a ventilation system to maintain a cool and dry environment, ideal for preserving perishable goods. The Romans also used terracotta pots and amphorae to store fruits and vegetables in their kitchens, ensuring they stayed fresh for longer periods of time.
