Saed News: Major General Sir John Malcolm, during his second trip to Iran, brought a delicious and tasty gift for the Shah of Iran, which the Iranians called "Sir John Malcolm's Plum."
According to the History Service of Saed News, John Malcolm was a British diplomat who brought the sweet potato seed to Iran in the 1800s and presented it as a gift to Fath-Ali Shah. Before that, sweet potatoes did not exist in Iran, and the people called it "Sir John Malcolm’s Plum." Later, however, the name "plum" for sweet potato fell out of use, and those who had traveled abroad adopted the French term "pomme de terre," which gradually became common.
