28. The Prussian King Frederick the Great (Frederick II) is famous for his military victories, but he also revolutionized German eating habits. How so?
From Quiz Glories of German Cooking
Answer:
He promoted cultivation of potatoes
Spanish explorers brought the potato from South America to Europe in the 16th century, but it didn't really take root in Germany. Too bad - it was generally nourishing, had a high yield per acre, and was cheaper than bread. German farmers clung to their traditional crops, and their practice of leaving a field fallow every third year. In the mid-18th century, Frederick mandated the cultivation of potatoes to help feed a burgeoning population.
Potato dumplings, boiled potatoes, roast potatoes, mashed potatoes, infinite varieties of potato salad ... thank you, your Majesty. By tradition, visitors to Frederick's grave leave a potato as well as flowers.
