Potatoes are an almost omnipotent ingredient.
Originating from the Andes Mountains in South America, they were introduced to China in the 16th century. As an imported product, they have high yield per acre and are easy to grow. Mrs. Jiang, having nothing better to do, planted half an acre of potatoes, which Jiang Feng could cook however he wanted—steam, boil, bake, fry, sauté, cook, deep-fry—you name it, but in the end, they were all for the pigs to eat.
Compared to leafy greens, Jiang Feng also preferred potatoes. Leafy greens only required fire control and a bit of seasoning, but it was different with potatoes, not only could he practice generous amounts of knifework and fire control, but he could also use more seasoning than when stir-frying greens.
Consequently, Sir Jiang's ways of scolding him also increased.
"Are those supposed to be potato slices? Why are you cutting them so thin? Are you cooking for immortals?"
