Turntable speed / pitch / RPM. Vinyl records are manufactured to be played back at a certain speed. Most 12 inch (diameter) long-play records are played back at 33 1/3rd revolutions per minute. Most 7 inch records require 45 RPM.
Jicama is a large, bulbous root vegetable. A bulb may weigh one or two pounds and has a rough 'n' tough brown skin which should be peeled before eating or cooking.
Yes, you need to peel a jicamaâs thick, papery skin, but please do not peel jicama skin with a vegetable peeler! A chefâs knife will give you much better (and safer) results. Cut a thin slice from the top and bottom of the jicama to create a flat surface on each end. Rest the jicama on its broadest cut end.
