1. Using the wrong type of potatoes. Choose higher starch potatoes (like Russets or Yukon golds) for the fluffiest, smoothest mash. They also absorb flavorings more easily. Waxy potatoes (such as red or white varieties) require more mashing to become creamy, which could lead to the dreaded potato paste..
Leather is a durable and flexible material created by tanning animal rawhide and skin, often cattle hide. It can be produced at manufacturing scales ranging from cottage industry to heavy industry.
Best Answer: PU leather is leather from the inner hide of the animal (usually a cow) because it's not the outer layer it has to be waterproofed with a polymer. So it is a real leather jacket, but like leather from a sun-burned cow that's peeled and you got the next layer down. On top of the PU leather is a finishing surface to give an external aspect like upper-layer leather. The inner layer gives the strength and suppleness, the outer layer gives the finish. It's the same leather that's used in most mid-range leather furniture. Hope that helps.
