Medieval European cuisine was often monotonous. Spices added depth, complexity, and variety to otherwise bland dishes.
Spices were rare and astronomically expensive due to long, perilous trade routes and monopolies. Displaying them signaled immense wealth and social standing.
Spices were believed to cure ailments, balance humors, and preserve health. They were staples in medieval apothecaries.
Before refrigeration, spices (especially pepper, cinnamon, cloves) helped mask spoilage and extend the shelf life of meats and fish.
Certain spices (e.g., frankincense, myrrh, saffron) were used in religious rites, making them objects of devotion as well as luxury.
Merchant cartels (like the Venetians, then Portuguese and Dutch) controlled supply chains, deliberately restricting availability to maintain high prices.
These factors combined to make spices the ultimate luxury commodity, driving the Age of Exploration.
