Dandan noodles is a Sichuan-style dish. It is called dandan because in the past street vendors in Sichuan carried a pole (dandan in Chinese) over their shoulders, with the noodles in a basket tied to one end and the accompanying sauce tied to the other.
Dandan combines fresh noodles with minced pork, peanuts, preserved vegetables, sliced scallions, in spicy sauce with Sichuan chili oil and pepper.
